CVE-2021-31294 WRITEUP MEDIUM WRITEUP
Redis < 6.2.0 - Reachable Assertion via Replica SET Command
Redis before 6cbea7d allows a replica to cause an assertion failure in a primary server by sending a non-administrative command (specifically, a SET command). NOTE: this was fixed for Redis 6.2.x and 7.x in 2021. Versions before 6.2 were not intended to have safety guarantees related to this.
CVSS 5.9
CVE-2024-31449 WRITEUP HIGH WRITEUP
Redis 2.8.18-6.2.15 - Authenticated Stack-based Buffer Overflow via Lua Bit Library
Redis is an open source, in-memory database that persists on disk. An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution. The problem exists in all versions of Redis with Lua scripting. This problem has been fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2021-32627 WRITEUP HIGH WRITEUP
Redis 5.0.0-5.0.13 - Remote Code Execution via Integer Overflow in Stream Elements
Redis is an open source, in-memory database that persists on disk. In affected versions an integer overflow bug in Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default proto-max-bulk-len and client-query-buffer-limit configuration parameters to very large values and constructing specially crafted very large stream elements. The problem is fixed in Redis 6.2.6, 6.0.16 and 5.0.14. For users unable to upgrade an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.
CVSS 7.5
CVE-2021-32628 WRITEUP HIGH WRITEUP
Redis 5.0.0-5.0.13 - Remote Code Execution via Ziplist Integer Overflow
Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the ziplist data structure used by all versions of Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves modifying the default ziplist configuration parameters (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value) to a very large value, and then constructing specially crafted commands to create very large ziplists. The problem is fixed in Redis versions 6.2.6, 6.0.16, 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the above configuration parameters. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.

CVE-2021-32675 WRITEUP HIGH WRITEUP
Redis 5.0.0-5.0.13 - Unauthenticated Denial of Service via RESP Request Memory Allocation
Redis is an open source, in-memory database that persists on disk. When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). An attacker delivering specially crafted requests over multiple connections can cause the server to allocate significant amount of memory. Because the same parsing mechanism is used to handle authentication requests, this vulnerability can also be exploited by unauthenticated users. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways: Using network access control tools like firewalls, iptables, security groups, etc. or Enabling TLS and requiring users to authenticate using client side certificates.

CVE-2021-32687 WRITEUP HIGH WRITEUP
Redis <6.2.6/<6.0.16/<5.0.14 - Heap Corruption via set-max-intset-entries
Redis is an open source, in-memory database that persists on disk. An integer overflow bug affecting all versions of Redis can be exploited to corrupt the heap and potentially be used to leak arbitrary contents of the heap or trigger remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration parameter to a very large value and constructing specially crafted commands to manipulate sets. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the set-max-intset-entries configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.

CVE-2021-32762 WRITEUP HIGH WRITEUP
Redis 5.0.0-5.0.13 - Integer Overflow in Multi-Bulk Reply Parsing
Redis is an open source, in-memory database that persists on disk. The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. This is a result of a vulnerability in the underlying hiredis library which does not perform an overflow check before calling the calloc() heap allocation function. This issue only impacts systems with heap allocators that do not perform their own overflow checks. Most modern systems do and are therefore not likely to be affected. Furthermore, by default redis-sentinel uses the jemalloc allocator which is also not vulnerable. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14.
CVSS 7.5
CVE-2022-35977 WRITEUP MEDIUM WRITEUP
Redis 6.0.0-6.0.16 - Authenticated Denial of Service via SETRANGE and SORT(_RO) Integer Overflow
Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted `SETRANGE` and `SORT(_RO)` commands can trigger an integer overflow, resulting with Redis attempting to allocate impossible amounts of memory and abort with an out-of-memory (OOM) panic. The problem is fixed in Redis versions 7.0.8, 6.2.9 and 6.0.17. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 5.5
CVE-2022-36021 WRITEUP MEDIUM WRITEUP
Redis <6.0.18, <6.2.11, <7.0.9 - DoS
Redis is an in-memory database that persists on disk.

CVE-2023-28856 WRITEUP MEDIUM WRITEUP
Redis < 6.0.19 - Authenticated Denial of Service via HINCRBYFLOAT Command
Redis is an open source, in-memory database that persists on disk. Authenticated users can use the `HINCRBYFLOAT` command to create an invalid hash field that will crash Redis on access in affected versions. This issue has been addressed in in versions 7.0.11, 6.2.12, and 6.0.19. Users are advised to upgrade. There are no known workarounds for this issue.
CVSS 5.5
CVE-2023-45145 WRITEUP LOW WRITEUP
Redis 2.6.0-6.2.13 - Unauthenticated Unauthorized Connection via Unix Socket Permission Race Condition
Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used, this creates a race condition that enables, during a short period of time, another process to establish an otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. Users are advised to upgrade. For users unable to upgrade, it is possible to work around the problem by disabling Unix sockets, starting Redis with a restrictive umask, or storing the Unix socket file in a protected directory.
CVSS 3.6
CVE-2024-31227 WRITEUP MEDIUM WRITEUP
Redis 7.0.0-7.2.5 - Authenticated Denial of Service via Malformed ACL Selector
Redis is an open source, in-memory database that persists on disk. An authenticated with sufficient privileges may create a malformed ACL selector which, when accessed, triggers a server panic and subsequent denial of service. The problem exists in Redis 7 prior to versions 7.2.6 and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 4.4
CVE-2024-31228 WRITEUP MEDIUM WRITEUP
Redis 2.2.5-6.2.15 - Authenticated Denial of Service via Long String Match Pattern Recursion
Redis is an open source, in-memory database that persists on disk. Authenticated users can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as `KEYS`, `SCAN`, `PSUBSCRIBE`, `FUNCTION LIST`, `COMMAND LIST` and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crash. This problem has been fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
