CVE-2024-31449
CVE-2024-31449 is a critical vulnerability in Redis, an open-source in-memory database. This flaw allows an authenticated user to execute arbitrary code remotely by exploiting a stack buffer overflow within the Lua scripting engine. Specifically, a crafted Lua script targeting the bit library triggers the overflow.
Even though the CVSS score is 0, the SOCRadar Vulnerability Risk Score (SVRS) of 40 suggests a moderate risk, emphasizing that although not critical, it is still an issue to resolve. All Redis versions with Lua scripting are affected until patched. Upgrade to Redis versions 6.2.16, 7.2.6, or 7.4.1 to mitigate this risk. This vulnerability is significant because it could allow attackers to gain complete control of the Redis server, leading to data breaches or service disruption. There are no known workarounds, highlighting the urgency of applying the patch.
Description
CVE-2024-31449 is a critical vulnerability in Redis, an open-source in-memory database. An authenticated user can exploit this vulnerability by using a specially crafted Lua script to trigger a stack buffer overflow in the bit library, potentially leading to remote code execution. The vulnerability affects all versions of Redis with Lua scripting and has been actively exploited in the wild.
