APC < 3.8.0 apcupsd Multiple Vulnerabilities
Critical Nessus Plugin ID 11484
SynopsisThe remote host is running an application which is affected by multiple vulnerabilities.
DescriptionThe remote host is running the apcupsd client which, according to its version number, is affected by multiple vulnerabilities :
- The configuration file '/var/run/apcupsd.pid' is by default world-writable. A local attacker could re-write this file with other process IDs in order to crash the affected system.
- An issue exists in the 'log_event' function which a local attacker could exploit in order to execute arbitrary code.
- Several buffer overflow vulnerabilities have been reported which a remote attacker could exploit in order to execute arbitrary code on the remote host.
*** Nessus solely relied on the version number of the
*** remote server, so this might be a false positive
SolutionUpgrading to acpupsd version 3.8.0 or newer reportedly fixes the issue.
