Tenable Security Center Multiple Vulnerabilities (TNS-2026-19)

high Nessus Plugin ID 328967

Synopsis

An instance of Security Center installed on the remote system is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable Security Center running on the remote host is between 6.7.0 and 6.8.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2026-19 advisory.

 - Redis is an in-memory data structure store. In redis-server from 7.2.0 until 8.6.3, the unblock client flow does not handle an error return from `processCommandAndResetClient` when re-executing a blocked command. If a blocked client is evicted during this flow, an authenticated attacker can trigger a use- after-free that may lead to remote code execution. This has been patched in version 8.6.3.
 (CVE-2026-23479)

 - Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3. (CVE-2026-25243)

 - RedisTimeSeries is a time-series module for Redis. In all versions before 1.12.14 of RedisTimeSeries, the module does not properly validate serialized values processed through the Redis RESTORE command. An authenticated attacker with permission to execute RESTORE on a server with the RedisTimeSeries module loaded can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This has been patched in version 1.12.14. (CVE-2026-25588)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Apply security patch SC-202607.1 or later.
