CVE-2002-0010 in Bugzilla
Summary
by MITRE
Bugzilla before 2.14.1 allows remote attackers to inject arbitrary SQL code and create files or gain privileges via (1) the sql parameter in buglist.cgi, (2) invalid field names from the "boolean chart" query in buglist.cgi, (3) the mybugslink parameter in userprefs.cgi, (4) a malformed bug ID in the buglist parameter in long_list.cgi, and (5) the value parameter in editusers.cgi, which allows groupset privileges to be modified by attackers with blessgroupset privileges.

The vulnerability described in CVE-2002-0010 represents a critical SQL injection flaw affecting Bugzilla versions prior to 2.14.1. This vulnerability stems from inadequate input validation and sanitization mechanisms within several CGI scripts that handle user-supplied data. The flaw allows remote attackers to execute arbitrary SQL commands against the backend database, potentially leading to complete system compromise and unauthorized access to sensitive information. The vulnerability manifests across multiple entry points within the Bugzilla application, making it particularly dangerous as attackers can exploit different vectors to achieve their objectives.
The technical implementation of this vulnerability occurs through improper parameter handling in several key CGI scripts including buglist.cgi, userprefs.cgi, long_list.cgi, and editusers.cgi. In buglist.cgi, the sql parameter and invalid field names from boolean chart queries create opportunities for attackers to inject malicious SQL code directly into database queries. The mybugslink parameter in userprefs.cgi and malformed bug IDs in long_list.cgi provide additional attack vectors that bypass normal input validation. The most concerning aspect involves the value parameter in editusers.cgi, which allows privilege escalation through groupset modifications when attackers possess blessgroupset privileges, creating a path for unauthorized privilege modification.
This vulnerability directly maps to CWE-89 SQL Injection, which is classified as a high-severity weakness in the Common Weakness Enumeration catalog. The attack pattern aligns with ATT&CK technique T1078 Valid Accounts, as successful exploitation could lead to unauthorized access to database credentials and system privileges. The operational impact extends beyond simple data theft to include complete database compromise, privilege escalation, and potential system takeover. Attackers could leverage these vulnerabilities to create arbitrary files on the system, modify user permissions, and access confidential bug reports and user information. The multi-vector nature of this vulnerability makes it particularly challenging to defend against, as each attack vector requires specific mitigation strategies.
The remediation approach for CVE-2002-0010 involves immediate upgrading to Bugzilla version 2.14.1 or later, which contains proper input validation and sanitization patches. Organizations should implement comprehensive parameter validation for all user-supplied inputs across all CGI scripts, employ prepared statements or parameterized queries to prevent SQL injection, and establish proper input filtering mechanisms. Network segmentation and access controls should be implemented to limit exposure of vulnerable systems, while regular security audits should verify that all input handling mechanisms properly sanitize user data. Additionally, implementing web application firewalls and intrusion detection systems can provide additional layers of protection against exploitation attempts. The vulnerability demonstrates the critical importance of input validation in web applications and highlights how seemingly minor implementation flaws can lead to catastrophic security breaches.
