CVE-2008-1502

CWE-79Published: March 25, 2008· Updated: Jun 16, 2026

4.3

CVSS v3.1

Official Description

The _bad_protocol_once function in phpgwapi/inc/class.kses.inc.php in KSES, as used in eGroupWare before 1.4.003, Moodle before 1.8.5, and other products, allows remote attackers to bypass HTML filtering and conduct cross-site scripting (XSS) attacks via a string containing crafted URL protocols.

Technical Analysis

CVE-2008-1502 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.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
