CWE-89Published: March 31, 2008· Updated: Jun 16, 2026
Official Description
The pnVarPrepForStore function in PostNuke 0.764 and earlier skips input sanitization when magic_quotes_runtime is enabled, which allows remote attackers to conduct SQL injection attacks and execute arbitrary SQL commands via input associated with server variables, as demonstrated by the CLIENT_IP HTTP header (HTTP_CLIENT_IP variable).
Technical Analysis
CVE-2008-1591 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
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-2008-1591. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
