CVE-2006-4842
CWE-20Published: October 12, 2006· Updated: Jun 16, 2026
3.6
CVSS v3.1
Official Description
The Netscape Portable Runtime (NSPR) API 4.6.1 and 4.6.2, as used in Sun Solaris 10, trusts user-specified environment variables for specifying log files even when running from setuid programs, which allows local users to create or overwrite arbitrary files.
Technical Analysis
CVE-2006-4842 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-2006-4842. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
