CVE-2009-1526
CWE-59Published: May 5, 2009· Updated: Jun 16, 2026
6.9
CVSS v3.1
Official Description
JBMC Software DirectAdmin before 1.334 allows local users to create or overwrite any file via a symlink attack on an arbitrary file in a certain temporary directory, related to a request for this temporary file in the PATH_INFO to the CMD_DB script during a backup action.
Technical Analysis
CVE-2009-1526 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-2009-1526. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
