CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 1CVE-2022-24735 – Lua scripts can be manipulated to overcome ACL rules in Redis
https://notcve.org/view.php?id=CVE-2022-24735
Redis is an in-memory database that persists on disk. By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis prior to version 7.0.0 or 6.2.7 can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. The Lua script execution environment in Redis provides some measures that prevent a script from creating side effects that persist and can affect the execution of the same, or different script, at a later time. Several weaknesses of these measures have been publicly known for a long time, but they had no security impact as the Redis security model did not endorse the concept of users or privileges. With the introduction of ACLs in Redis 6.0, these weaknesses can be exploited by a less privileged users to inject Lua code that will execute at a later time, when a privileged user executes a Lua script. • https://github.com/redis/redis/pull/10651 https://github.com/redis/redis/releases/tag/6.2.7 https://github.com/redis/redis/releases/tag/7.0.0 https://github.com/redis/redis/security/advisories/GHSA-647m-2wmq-qmvq https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J4ZK3675DGHVVDOFLJN7WX6YYH27GPMK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VPYKSG7LKUJGVM2P72EHXKVRVRWHLORX https://lists.fedoraproject.org/archives/list/ • CWE-94: Improper Control of Generation of Code ('Code Injection') •

https://notcve.org/view.php?id=CVE-2021-32672
Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. Redis es una base de datos en memoria de código abierto que persiste en el disco. • https://github.com/redis/redis/commit/6ac3c0b7abd35f37201ed2d6298ecef4ea1ae1dd https://github.com/redis/redis/security/advisories/GHSA-9mj9-xx53-qmxm https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WR5WKJWXD4D6S3DJCZ56V74ESLTDQRAB https://security.gentoo.org/gls • CWE-125: Out-of-bounds Read •
CVSS: 8.8EPSS: 2%CPEs: 13EXPL: 0CVE-2021-32626 – Lua scripts can overflow the heap-based Lua stack in Redis
https://notcve.org/view.php?id=CVE-2021-32626
Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. This problem exists in all versions of Redis with Lua scripting support, starting from 2.6. The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. • https://github.com/redis/redis/commit/666ed7facf4524bf6d19b11b20faa2cf93fdf591 https://github.com/redis/redis/security/advisories/GHSA-p486-xggp-782c https://lists.apache.org/thread.html/r75490c61c2cb7b6ae2c81238fd52ae13636c60435abcd732d41531a0%40%3Ccommits.druid.apache.org%3E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HTYQ5ZF37HNGTZWVNJD3VXP7I6MEEF42 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VL5KXFN3ATM7IIM7Q4O4PWTSRGZ5744Z https://lists.fedoraproject.org/arch • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 1%CPEs: 8EXPL: 0CVE-2021-32761 – Integer overflow issues with *BIT commands on 32-bit systems
https://notcve.org/view.php?id=CVE-2021-32761
Redis is an in-memory database that persists on disk. A vulnerability involving out-of-bounds read and integer overflow to buffer overflow exists starting with version 2.2 and prior to versions 5.0.13, 6.0.15, and 6.2.5. On 32-bit systems, Redis `*BIT*` command are vulnerable to integer overflow that can potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code execution. The vulnerability involves changing the default `proto-max-bulk-len` configuration parameter to a very large value and constructing specially crafted commands bit commands. This problem only affects Redis on 32-bit platforms, or compiled as a 32-bit binary. • https://github.com/redis/redis/security/advisories/GHSA-8wxq-j7rp-g8wj https://lists.debian.org/debian-lts-announce/2021/07/msg00017.html https://lists.debian.org/debian-lts-announce/2021/08/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6O7AUOROBYGP5IMGJPC5HZ3R2RB6GZ5X https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VGX7RRAWGXWXEAKJTQYSDSBO2BC3SAHD https://security.gentoo.org/glsa/202209-17 https://security.netapp&# • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •

https://notcve.org/view.php?id=CVE-2021-3470
A heap overflow issue was found in Redis in versions before 5.0.10, before 6.0.9 and before 6.2.0 when using a heap allocator other than jemalloc or glibc's malloc, leading to potential out of bound write or process crash. Effectively this flaw does not affect the vast majority of users, who use jemalloc or glibc malloc. Se encontró un problema de desbordamiento de pila en Redis en las versiones anteriores a 5.0.10, versiones anteriores a 6.0.9 y versiones anteriores a 6.2.0, cuando se usaba un asignador de pila que no fuera jemalloc o malloc de glibc, conllevando a un posible bloqueo del proceso o de escritura fuera de límites. Efectivamente, este fallo no afecta a la gran mayoría de usuarios que usan jemalloc o glibc malloc. • https://bugzilla.redhat.com/show_bug.cgi?id=1943623 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
