These vulnerabilities could allow authenticated users to execute arbitrary commands, escalate privileges, and access unauthorized files, posing severe threats to the integrity and security of affected systems.

CVE-2024-45076

The most critical of the identified vulnerabilities, CVE-2024-45076, allows an authenticated user to upload and execute arbitrary files on the underlying operating system.

This vulnerability carries a CVSS Base Score of 9.9, reflecting its high severity. The potential for exploitation is significant, as it could enable attackers to execute commands that compromise system security and data integrity.

• CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H)
• Details: An authenticated developer user can write an OSCommand.cnf file and execute arbitrary commands, effectively gaining control over the server.

CVE-2024-45075

CVE-2024-45075 presents another serious risk, with a CVSS Base Score of 8.8. This vulnerability allows an authenticated user to create scheduler tasks, escalating their privileges to that of an administrator due to missing authentication checks.

The implications of this vulnerability are profound, as it enables unauthorized access to critical system functions.

• CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
• Details: An authenticated developer can utilize the scheduler service to create a user and elevate that user to an administrator using the runAsUser function.

CVE-2024-45074

The third vulnerability, CVE-2024-45074, with a CVSS Base Score 6.5, allows directory traversal. An attacker can send specially crafted URL requests containing “dot dot” sequences (/../) to view arbitrary files on the system.

Although less severe than the other vulnerabilities, it poses a significant threat by potentially exposing sensitive information.

• CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
• Details: Even when checkFileRead is set, an authenticated developer can read files outside the intended directories.

Affected Products and Versions

The vulnerabilities affect IBM webMethods Integration Server version 10.15. Organizations using this version are urged to assess their systems and apply necessary patches to mitigate the risks.

IBM has strongly recommended that organizations address these vulnerabilities promptly. The company advises users to apply available patches and updates to secure their systems against potential exploits.

Additionally, organizations should review their access controls and authentication mechanisms to prevent unauthorized access and privilege escalation.

The identified vulnerabilities in IBM’s webMethods Integration Server highlight critical security challenges that organizations must address to protect their systems and data.

These vulnerabilities pose significant risks, including the potential for arbitrary command execution and unauthorized access, that require immediate action.

By applying recommended patches and strengthening security protocols, organizations can mitigate these threats and maintain the integrity of their IT environments.
