CWE-78Published: September 10, 2013· Updated: Jun 16, 2026
7.2
CVSS v3.1
Official Description
The close_connections function in /opt/cma/bin/clear_keys.pl in Sophos Web Appliance before 3.7.9.1 and 3.8 before 3.8.1.1 allows local users to gain privileges via shell metacharacters in the second argument.
Technical Analysis
CVE-2013-4984 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2013-4984. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
