Comprehensive Technical Analysis of EUVD-2024-45781

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-45781 affects IBM Cognos Analytics versions 11.2.0 through 11.2.4 FP4 and 12.0.0 through 12.0.4. It is classified as an Expression Language (EL) Injection vulnerability. The CVSS (Common Vulnerability Scoring System) base score of 9.0 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): High (H) - Exploiting the vulnerability requires specialized conditions or knowledge.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the exploit to succeed.
• Scope (S): Changed (C) - The vulnerability affects a different security scope.
• Confidentiality (C): High (H) - There is a high impact on the confidentiality of the data.
• Integrity (I): High (H) - There is a high impact on the integrity of the data.
• Availability (A): High (H) - There is a high impact on the availability of the system.

Given the high impact on confidentiality, integrity, and availability, this vulnerability poses a significant risk to organizations using the affected versions of IBM Cognos Analytics.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through specially crafted EL statements. An attacker could exploit this vulnerability by:

• Injecting Malicious EL Statements: Crafting and injecting EL statements that can manipulate the server's behavior.
• Exposing Sensitive Information: Using EL injection to extract sensitive data from the server.
• Consuming Memory Resources: Crafting EL statements that cause excessive memory consumption, leading to a denial of service (DoS).
• Causing Server Crash: Exploiting the vulnerability to crash the server, resulting in service disruption.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of IBM Cognos Analytics:

• 11.2.0 through 11.2.4 FP4
• 12.0.0 through 12.0.4

Organizations using these versions are at risk and should prioritize mitigation efforts.
