CVE-2004-1018

NVD-CWE-OtherPublished: January 10, 2005· Updated: Jun 16, 2026

10.0
CVSS v3.1

Official Description

Multiple integer handling errors in PHP before 4.3.10 allow attackers to bypass safe mode restrictions, cause a denial of service, or execute arbitrary code via (1) a negative offset value to the shmop_write function, (2) an "integer overflow/underflow" in the pack function, or (3) an "integer overflow/underflow" in the unpack function. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

Technical Analysis

CVE-2004-1018 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-2004-1018. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
