Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in Redis versions 8.2.1 and below allows an authenticated user to use a specially crafted Lua script to cause an integer overflow, which can potentially lead to remote code execution. It affects all versions of Redis with Lua scripting and is fixed in version 8.2.2.
How can this vulnerability impact me? :
The vulnerability can allow an authenticated user to execute arbitrary code remotely on the Redis server, which can lead to full compromise of the system, including data loss, unauthorized access, and disruption of services.
What immediate steps should I take to mitigate this vulnerability?
Upgrade Redis to version 8.2.2 or later, as this version contains the fix for the integer overflow vulnerability in Lua scripting. Until the upgrade can be performed, restrict authenticated user access to Redis instances and limit the use of Lua scripts to trusted users only.
