CVE-2005-1633 in JGS-Portal
Summary
by MITRE
Multiple SQL injection vulnerabilities in JGS-XA JGS-Portal 3.0.2 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) anzahl_beitraege parameter to jgs_portal.php, 2) year parameter to (jgs_portal_statistik.php, 3) year parameter to (jgs_portal_beitraggraf.php, 4) tag parameter to (jgs_portal_viewsgraf.php, 5) year parameter to (jgs_portal_themengraf.php, 6) year parameter to (jgs_portal_mitgraf.php, 7) id parameter to jgs_portal_sponsor.php, or (8) the Accept-Language header to jgs_portal_log.php.

The CVE-2005-1633 vulnerability represents a critical SQL injection flaw affecting JGS-XA JGS-Portal versions 3.0.2 and earlier, exposing multiple attack vectors that enable remote code execution through database manipulation. This vulnerability stems from inadequate input validation and sanitization within several key PHP scripts that process user-supplied parameters. The affected components include jgs_portal.php, jgs_portal_statistik.php, jgs_portal_beitraggraf.php, jgs_portal_viewsgraf.php, jgs_portal_themengraf.php, jgs_portal_mitgraf.php, jgs_portal_sponsor.php, and jgs_portal_log.php, each processing distinct input parameters that bypass proper security controls. The vulnerability operates under CWE-89 which categorizes SQL injection as a weakness where untrusted data is directly incorporated into SQL commands without proper escaping or parameterization, creating a direct pathway for malicious actors to manipulate database queries. The attack surface expands significantly through the Accept-Language header processing in jgs_portal_log.php, which demonstrates how seemingly innocuous HTTP headers can become exploitation vectors for database attacks.
The technical exploitation of these vulnerabilities occurs when remote attackers inject malicious SQL payloads through the identified parameters, allowing them to bypass authentication mechanisms, extract sensitive data, modify database contents, or even execute arbitrary system commands depending on the database backend and privilege levels. The anzahl_beitraege parameter in jgs_portal.php represents a straightforward injection point where numeric input is not properly validated, while the year parameters across multiple statistical and graphical reporting scripts provide consistent attack vectors that leverage the same underlying flaw. The tag parameter in jgs_portal_viewsgraf.php and the id parameter in jgs_portal_sponsor.php further extend the attack surface by targeting different data processing functions within the application's reporting infrastructure. The inclusion of the Accept-Language header as an attack vector in jgs_portal_log.php demonstrates the sophisticated nature of the vulnerability, where headers typically used for content negotiation become potential injection points.
The operational impact of CVE-2005-1633 extends beyond simple data theft to encompass complete system compromise and unauthorized access to sensitive organizational information. Attackers can exploit these vulnerabilities to access user credentials, personal data, financial records, and other confidential information stored within the portal's database. The vulnerability's presence in statistical and graphical reporting functions means that legitimate user activities may be exploited to gain unauthorized database access, making detection more challenging. Organizations using affected versions face risks of data breaches, regulatory compliance violations, and potential legal consequences due to inadequate security controls. The vulnerability also enables attackers to escalate privileges and potentially gain shell access to the underlying server, representing a severe threat to system integrity and availability.
Mitigation strategies for CVE-2005-1633 must focus on immediate patching of the affected JGS-Portal versions and implementation of proper input validation mechanisms. Organizations should deploy web application firewalls and implement parameterized queries to prevent SQL injection attacks, ensuring that all user inputs are properly escaped or validated before database processing. The recommended approach includes applying the vendor-supplied security patches and upgrading to supported versions of the JGS-Portal software. Additionally, implementing strict input filtering, using stored procedures, and employing proper database access controls can significantly reduce the attack surface. Security monitoring should be enhanced to detect anomalous database queries and unusual traffic patterns that may indicate exploitation attempts. The vulnerability aligns with ATT&CK technique T1190 for exploit known vulnerabilities, emphasizing the importance of maintaining up-to-date security patches and implementing comprehensive application security controls. Organizations should also conduct thorough security assessments to identify similar vulnerabilities in other applications and implement automated vulnerability scanning tools to prevent future occurrences of this class of attack.
