CVE-2015-1158
CWE-254Published: June 26, 2015· Updated: Jun 17, 2026
Official Description
The add_job function in scheduler/ipp.c in cupsd in CUPS before 2.0.3 performs incorrect free operations for multiple-value job-originating-host-name attributes, which allows remote attackers to trigger data corruption for reference-counted strings via a crafted (1) IPP_CREATE_JOB or (2) IPP_PRINT_JOB request, as demonstrated by replacing the configuration file and consequently executing arbitrary code.
Technical Analysis
CVE-2015-1158 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-2015-1158. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
