BIG-IP Local Traffic Manager - Exposure of Sensitive Information via Session Tickets
A BIG-IP virtual server configured with a Client SSL profile that has the non-default Session Tickets option enabled may leak up to 31 bytes of uninitialized memory. A remote attacker may exploit this vulnerability to obtain Secure Sockets Layer (SSL) session IDs from other sessions. It is possible that other data from uninitialized memory may be returned as well.

Nextcloud Server < 9.0.52 and ownCloud Server < 9.0.4 - Stored Cross-Site Scripting via Download Log
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are vulnerable to a log pollution vulnerability potentially leading to a local XSS. The download log functionality in the admin screen is delivering the log in JSON format to the end-user. The file was delivered with an attachment disposition forcing the browser to download the document. However, Firefox running on Microsoft Windows would offer the user to open the data in the browser as an HTML document. Thus any injected data in the log would be executed.
CVSS 6.1
Nextcloud Server < 9.0.52 and ownCloud Server < 9.0.4 - Content Spoofing in Files App Location Bar
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are vulnerable to a content-spoofing attack in the files app. The location bar in the files app was not verifying the passed parameters. An attacker could craft an invalid link to a fake directory structure and use this to display an attacker-controlled error message to the user.
CVSS 5.3
Nextcloud Server < 9.0.52 & ownCloud Server < 9.0.4 - Authenticated Arbitrary File Write via WebDAV COPY
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying edit check permissions on WebDAV copy actions. The WebDAV endpoint was not properly checking the permission on a WebDAV COPY action. This allowed an authenticated attacker with access to a read-only share to put new files in there. It was not possible to modify existing files.
CVSS 4.3
Nextcloud Server < 9.0.52 & ownCloud Server < 9.0.4 - Unauthenticated File Restore Privilege Bypass
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying restore privileges when restoring a file. The restore capability of Nextcloud/ownCloud was not verifying whether a user has only read-only access to a share. Thus a user with read-only access was able to restore old versions.
CVSS 4.3
Nextcloud Server <9.0.54/10.0.1 & ownCloud Server <9.1.2/9.0.6/8.2.9 - SMB Auth Bypass
Nextcloud Server before 9.0.54 and 10.0.1 & ownCloud Server before 9.1.2, 9.0.6, and 8.2.9 suffer from SMB User Authentication Bypass. Nextcloud/ownCloud include an optional and not by default enabled SMB authentication component that allows authenticating users against an SMB server. This backend is implemented in a way that tries to connect to a SMB server and if that succeeded consider the user logged-in. The backend did not properly take into account SMB servers that have any kind of anonymous auth configured. This is the default on SMB servers nowadays and allows an unauthenticated attacker to gain access to an account without valid credentials. Note: The SMB backend is disabled by default and requires manual configuration in the Nextcloud/ownCloud config file. If you have not configured the SMB backend then you're not affected by this vulnerability.
CVSS 8.1

CVSS 8.1
Nextcloud Server < 9.0.54 and 10.0.0 - Improper Authorization in Sharing Backend
Nextcloud Server before 9.0.54 and 10.0.0 suffers from an improper authorization check on removing shares. The Sharing Backend as implemented in Nextcloud does differentiate between shares to users and groups. In case of a received group share, users should be able to unshare the file to themselves but not to the whole group. The previous API implementation simply unshared the file to all users in the group.
CVSS 4.3
Nextcloud Server < 10.0.1 & ownCloud Server < 9.0.6 and 9.1.2 - Stored Cross-Site Scripting in CardDAV Image Export
Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Stored XSS in CardDAV image export. The CardDAV image export functionality as implemented in Nextcloud/ownCloud allows the download of images stored within a vCard. Due to not performing any kind of verification on the image content this is prone to a stored Cross-Site Scripting attack.
CVSS 5.4
Nextcloud Server < 10.0.1 and ownCloud Server < 9.0.6 and 9.1.2 - Reflected Cross-Site Scripting in Gallery Application
Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Reflected XSS in the Gallery application. The gallery app was not properly sanitizing exception messages from the Nextcloud/ownCloud server. Due to an endpoint where an attacker could influence the error message, this led to a reflected Cross-Site-Scripting vulnerability.
CVSS 6.1

CVSS 5.3
Revive Adserver < 3.2.5 and 4.0.0 - Reflected Cross-Site Scripting via Web Installer Parameters
Revive Adserver before 3.2.5 and 4.0.0 suffers from Reflected XSS. The Revive Adserver web installer scripts were vulnerable to a reflected XSS attack via the dbHost, dbUser, and possibly other parameters. It has to be noted that the window for such attack vectors to be possible is extremely narrow and it is very unlikely that such an attack could be actually effective.
CVSS 5.4
libtiff - Heap-Based Buffer Overflow in Predictor Function
tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling. Reported as MSVR 35105, aka "Predictor heap-buffer-overflow."

Alcatel-Lucent OmniVista 8770 2.0-3.0 - Unauthenticated Remote Code Execution via GIOP ORB Interface
Alcatel-Lucent OmniVista 8770 2.0 through 3.0 exposes different ORBs interfaces, which can be queried using the GIOP protocol on TCP port 30024. An attacker can bypass authentication, and OmniVista invokes methods (AddJobSet, AddJob, and ExecuteNow) that can be used to run arbitrary commands on the server, with the privilege of NT AUTHORITY\SYSTEM on the server. NOTE: The discoverer states "The vendor position is to refer to the technical guidelines of the product security deployment to mitigate this issue, which means applying proper firewall rules to prevent unauthorised clients to connect to the OmniVista server."
