CISA Warns of Critical Vulnerability in Mobility46 Software

The Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent alert regarding a critical vulnerability in the Mobility46.se platform, a Swedish mobility management software solution. The vulnerability, tracked as CVE-2024-2846, affects versions 1.0 through 1.3 and allows unauthenticated remote code execution with system-level privileges.

The flaw exists in the platform's authentication module, where improper input validation enables attackers to bypass security controls and execute arbitrary commands on affected systems. CISA has assigned this vulnerability a CVSS score of 9.8 out of 10, indicating critical severity.

Technical Details

The vulnerability stems from a buffer overflow in the authentication handler component. Attackers can exploit this by sending specially crafted authentication requests that overflow the buffer and overwrite adjacent memory regions, including the instruction pointer. This allows execution of malicious code without requiring valid credentials.

Affected versions include:

• Mobility46.se v1.0
• Mobility46.se v1.1
• Mobility46.se v1.2
• Mobility46.se v1.3

Impact Assessment

Successful exploitation could enable attackers to:

• Gain complete control of affected systems
• Access sensitive user data and configuration files
• Deploy additional malware or ransomware
• Pivot to other systems within the network
• Disrupt mobility services for organizations using the platform

Mitigation Steps

Mobility46 has released version 1.4 which addresses this vulnerability. Organizations using affected versions should:

1. Immediately upgrade to Mobility46.se v1.4
2. Apply the security patch as soon as possible
3. Monitor system logs for suspicious activity
4. Consider network segmentation for affected systems
5. Review access controls and authentication policies

The patch is available through the official Mobility46.se update mechanism or can be downloaded directly from the vendor's support portal.

CISA urges all organizations using Mobility46.se to prioritize this update due to the critical nature of the vulnerability and the ease of exploitation. The agency notes that active exploitation attempts have been detected in the wild, targeting transportation and logistics companies primarily.

For organizations unable to immediately apply the patch, CISA recommends implementing network-level controls to restrict access to the affected authentication endpoints until remediation can be completed.
