The version of redis installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-25155 advisory.
SRANDMEMBER
, ZRANDMEMBER
, and HRANDFIELD
commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. This problem affects all Redis versions.Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of redis installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected
by a vulnerability as referenced in the CVE-2023-25155 advisory.
- Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted
`SRANDMEMBER`, `ZRANDMEMBER`, and `HRANDFIELD` commands can trigger an integer overflow, resulting in a
runtime assertion and termination of the Redis server process. This problem affects all Redis versions.
Patches were released in Redis version(s) 6.0.18, 6.2.11 and 7.0.9. (CVE-2023-25155)
