CVE ID: CVE-2024-51466

Description: IBM Cognos Analytics versions 11.2.0 through 11.2.4 FP4 and 12.0.0 through 12.0.4 are vulnerable to an Expression Language (EL) Injection vulnerability. This vulnerability allows a remote attacker to exploit the system using a specially crafted EL statement, potentially leading to the exposure of sensitive information, consumption of memory resources, and/or causing the server to crash.

CVSS Score: 9

Severity Evaluation:

• Criticality: The CVSS score of 9 indicates a critical vulnerability. This high score is due to the potential for significant impact, including data breaches, denial of service, and resource exhaustion.
• Impact: The vulnerability can result in unauthorized access to sensitive information, degradation of system performance, and potential system crashes, which can disrupt business operations.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can remotely exploit the vulnerability by sending specially crafted EL statements to the affected IBM Cognos Analytics server.
• Web Interface: The attacker can leverage the web interface of IBM Cognos Analytics to inject malicious EL statements.

Exploitation Methods:

• Crafted EL Statements: The attacker can craft EL statements designed to extract sensitive information, consume excessive memory resources, or cause the server to crash.
• Automated Tools: Attackers may use automated tools to scan for vulnerable versions of IBM Cognos Analytics and exploit the vulnerability en masse.

3. Affected Systems and Software Versions

Affected Versions:

• IBM Cognos Analytics 11.2.0 through 11.2.4 FP4
• IBM Cognos Analytics 12.0.0 through 12.0.4
