Paginator < 1.0.0 - Remote Code Execution via paginate() Function Input
There is a vulnerability in Paginator (Elixir/Hex package) which makes it susceptible to Remote Code Execution (RCE) attacks via input parameters to the paginate() function. This will potentially affect all current users of Paginator prior to version 1.0.0. The vulnerability has been patched in version 1.0.0 and all users should upgrade to this version immediately. Note that this patched version uses a dependency that requires an Elixir version >=1.5.
CVSS 9.0
CVE-2020-15160 WRITEUP CRITICAL
PrestaShop <1.7.6.8 - Blind SQL Injection
PrestaShop from version 1.7.5.0 and before version 1.7.6.8 is vulnerable to a blind SQL Injection attack in the Catalog Product edition page with location parameter. The problem is fixed in 1.7.6.8
CVSS 9.8
CVE-2020-15175 WRITEUP HIGH
GLPI < 9.5.2 - Unauthenticated Arbitrary File Deletion and Information Disclosure via pluginimage.send.php
In GLPI before version 9.5.2, the `​pluginimage.send.php​` endpoint allows a user to specify an image from a plugin. The parameters can be maliciously crafted to instead delete the .htaccess file for the files directory. Any user becomes able to read all the files and folders contained in “/files/”. Some of the sensitive information that is compromised are the user sessions, logs, and more. An attacker would be able to get the Administrators session token and use that to authenticate. The issue is patched in version 9.5.2.
CVSS 7.4
CVE-2020-15187 WRITEUP LOW
Helm <2.16.11, 3.3.2 - Local Execution
In Helm before versions 2.16.11 and 3.3.2, a Helm plugin can contain duplicates of the same entry, with the last one always used. If a plugin is compromised, this lowers the level of access that an attacker needs to modify a plugin's install hooks, causing a local execution attack. To perform this attack, an attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded (which can occur during a MITM attack on a non-SSL connection). This issue has been patched in Helm 2.16.11 and Helm 3.3.2. As a possible workaround make sure to install plugins using a secure connection protocol like SSL.
CVSS 3.0
CVE-2020-15202 WRITEUP CRITICAL
Tensorflow <2.3.1 - Memory Corruption
In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `Shard` API in TensorFlow expects the last argument to be a function taking two `int64` (i.e., `long long`) arguments. However, there are several places in TensorFlow where a lambda taking `int` or `int32` arguments is being used. In these cases, if the amount of work to be parallelized is large enough, integer truncation occurs. Depending on how the two arguments of the lambda are used, this can result in segfaults, read/write outside of heap allocated arrays, stack overflows, or data corruption. The issue is patched in commits 27b417360cbd671ef55915e4bb6bb06af8b8a832 and ca8c013b5e97b1373b3bb1c97ea655e69f31a575, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.

CVE-2020-15211 WRITEUP MEDIUM
TensorFlow Lite <2.3.1 - Info Disclosure
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of tensors that is owned by the subgraph. This results in a pattern of double array indexing when trying to get the data of each tensor. However, some operators can have some tensors be optional. To handle this scenario, the flatbuffer model uses a negative `-1` value as index for these tensors. This results in special casing during validation at model loading time. Unfortunately, this means that the `-1` index is a valid tensor index for any operator, including those that don't expect optional inputs and including for output tensors. Thus, this allows writing and reading from outside the bounds of heap allocated arrays, although only at a specific offset from the start of these arrays. This results in both read and write gadgets, albeit very limited in scope. The issue is patched in several commits (46d5b0852, 00302787b7, e11f5558, cd31fd0ce, 1970c21, and fff2c83), and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1. A potential workaround would be to add a custom `Verifier` to the model loading code to ensure that only operators which accept optional inputs use the `-1` special value and only for the tensors that they expect to be optional. Since this allow-list type approach is erro-prone, we advise upgrading to the patched code.

CVE-2020-15216 WRITEUP MEDIUM
goxmldsig < 1.1.0 - Cryptographic Signature Verification Bypass via Crafted XML File
In goxmldsig (XML Digital Signatures implemented in pure Go) before version 1.1.0, with a carefully crafted XML file, an attacker can completely bypass signature validation and pass off an altered file as a signed one. A patch is available, all users of goxmldsig should upgrade to at least revision f6188febf0c29d7ffe26a0436212b19cb9615e64 or version 1.1.0
CVSS 5.3
CVE-2020-15224 WRITEUP MEDIUM
Open Enclave <0.12.0 - Info Disclosure
In Open Enclave before version 0.12.0, an information disclosure vulnerability exists when an enclave application using the syscalls provided by the sockets.edl is loaded by a malicious host application. An attacker who successfully exploited the vulnerability could read privileged data from the enclave heap across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information otherwise considered confidential in an enclave, which could be used in further compromises. The issue has been addressed in version 0.12.0 and the current master branch. Users will need to to recompile their applications against the patched libraries to be protected from this vulnerability.

CVE-2020-15229 WRITEUP HIGH
Singularity <3.6.3 - Path Traversal
Singularity (an open source container platform) from version 3.1.1 through 3.6.3 has a vulnerability. Due to insecure handling of path traversal and the lack of path sanitization within `unsquashfs`, it is possible to overwrite/create any files on the host filesystem during the extraction with a crafted squashfs filesystem. The extraction occurs automatically for unprivileged (either installation or with `allow setuid = no`) run of Singularity when a user attempt to run an image which is a local SIF image or a single file containing a squashfs filesystem and is coming from remote sources `library://` or `shub://`. Image build is also impacted in a more serious way as it can be used by a root user, allowing an attacker to overwrite/create files leading to a system compromise, so far bootstrap methods `library`, `shub` and `localimage` are triggering the squashfs extraction. This issue is addressed in Singularity 3.6.4. All users are advised to upgrade to 3.6.4 especially if they use Singularity mainly for building image as root user. There is no solid workaround except to temporary avoid to use unprivileged mode with single file images in favor of sandbox images instead. Regarding image build, temporary avoid to build from `library` and `shub` sources and as much as possible use `--fakeroot` or a VM for that.

CVE-2020-15244 WRITEUP HIGH
Magento <19.4.8-20.0.4 - Code Injection
In Magento (rubygems openmage/magento-lts package) before versions 19.4.8 and 20.0.4, an admin user can generate soap credentials that can be used to trigger RCE via PHP Object Injection through product attributes and a product. The issue is patched in versions 19.4.8 and 20.0.4.

CVE-2020-15250 WRITEUP MEDIUM
JUnit4 4.7-4.13 - Local Information Disclosure via TemporaryFolder Rule
In JUnit4 from version 4.7 and before 4.13.1, the test rule TemporaryFolder contains a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users to overwrite the contents of these directories or files. This is purely an information disclosure vulnerability. This vulnerability impacts you if the JUnit tests write sensitive information, like API keys or passwords, into the temporary folder, and the JUnit tests execute in an environment where the OS has other untrusted users. Because certain JDK file system APIs were only added in JDK 1.7, this this fix is dependent upon the version of the JDK you are using. For Java 1.7 and higher users: this vulnerability is fixed in 4.13.1. For Java 1.6 and lower users: no patch is available, you must use the workaround below. If you are unable to patch, or are stuck running on Java 1.6, specifying the `java.io.tmpdir` system environment variable to a directory that is exclusively owned by the executing user will fix this vulnerability. For more information, including an example of vulnerable code, see the referenced GitHub Security Advisory.

CVE-2020-15253 WRITEUP HIGH
grocy < 2.7.1 - Authenticated Stored Cross-Site Scripting via Shopping List Deletion
Versions of Grocy <= 2.7.1 are vulnerable to Cross-Site Scripting via the Create Shopping List module, that is rendered upon deleting that Shopping List. The issue was also found in users, batteries, chores, equipment, locations, quantity units, shopping locations, tasks, taskcategories, product groups, recipes and products. Authentication is required to exploit these issues and Grocy should not be publicly exposed. The linked reference details a proof-of-concept.

CVE-2020-15255 WRITEUP HIGH
Anuko Time Tracker <1.19.23.5325 - Info Disclosure
In Anuko Time Tracker before verion 1.19.23.5325, due to not properly filtered user input a CSV export of a report could contain cells that are treated as formulas by spreadsheet software (for example, when a cell value starts with an equal sign). This is fixed in version 1.19.23.5325.
CVSS 8.7
CVE-2020-15257 WRITEUP MEDIUM
containerd <1.3.9 and <1.4.3 - Privilege Escalation
containerd is an industry-standard container runtime and is available as a daemon for Linux and Windows. In containerd before versions 1.3.9 and 1.4.3, the containerd-shim API is improperly exposed to host network containers. Access controls for the shim’s API socket verified that the connecting process had an effective UID of 0, but did not otherwise restrict access to the abstract Unix domain socket. This would allow malicious containers running in the same network namespace as the shim, with an effective UID of 0 but otherwise reduced privileges, to cause new processes to be run with elevated privileges. This vulnerability has been fixed in containerd 1.3.9 and 1.4.3. Users should update to these versions as soon as they are released. It should be noted that containers started with an old version of containerd-shim should be stopped and restarted, as running containers will continue to be vulnerable even after an upgrade. If you are not providing the ability for untrusted users to start containers in the same network namespace as the shim (typically the "host" network namespace, for example with docker run --net=host or hostNetwork: true in a Kubernetes pod) and run with an effective UID of 0, you are not vulnerable to this issue. If you are running containers with a vulnerable configuration, you can deny access to all abstract sockets with AppArmor by adding a line similar to deny unix addr=@**, to your policy. It is best practice to run containers with a reduced set of privileges, with a non-zero UID, and with isolated namespaces. The containerd maintainers strongly advise against sharing namespaces with the host. Reducing the set of isolation mechanisms used for a container necessarily increases that container's privilege, regardless of what container runtime is used for running that container.
CVSS 5.2
CVE-2020-15261 WRITEUP HIGH
Veyon Service <4.4.2 - Privilege Escalation
On Windows the Veyon Service before version 4.4.2 contains an unquoted service path vulnerability, allowing locally authenticated users with administrative privileges to run malicious executables with LocalSystem privileges. Since Veyon users (both students and teachers) usually don't have administrative privileges, this vulnerability is only dangerous in anyway unsafe setups. The problem has been fixed in version 4.4.2. As a workaround, the exploitation of the vulnerability can be prevented by revoking administrative privileges from all potentially untrustworthy users.
