CVE-2025-48742: CWE-306 Missing Authentication for Critical Function in SIGB PMB
The installer in SIGB PMB before and fixed in v.8.0.1.2 allows remote code execution.
AI Analysis
Technical Summary
CVE-2025-48742 is a vulnerability identified in the SIGB PMB product, specifically affecting versions prior to 8.0.1.2. The root cause of this vulnerability is a missing authentication mechanism for a critical function within the installer component of SIGB PMB. This flaw corresponds to CWE-306, which denotes 'Missing Authentication for Critical Function.' Due to the lack of authentication, an unauthenticated remote attacker can exploit this vulnerability to execute arbitrary code on the affected system. The vulnerability is remotely exploitable over the network without requiring any user interaction or privileges, but the attack complexity is rated as high, indicating some non-trivial conditions must be met for successful exploitation. The CVSS v3.1 base score is 5.4 (medium severity), reflecting limited impact on confidentiality and integrity, and no impact on availability. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The vulnerability was published on May 27, 2025, and no known exploits are currently reported in the wild. The lack of authentication on the installer function is critical because installers typically have elevated privileges and control over software deployment, making this a significant security risk if exploited. The vendor has addressed this issue in version 8.0.1.2, and users of earlier versions are advised to upgrade promptly.
Potential Impact
For European organizations using SIGB PMB, this vulnerability poses a moderate risk. Successful exploitation could allow remote attackers to execute arbitrary code, potentially leading to unauthorized access, data manipulation, or further lateral movement within the network. While the CVSS score indicates medium severity, the actual impact depends on the deployment context of SIGB PMB. If the product is used in critical infrastructure, government, or enterprise environments, the risk escalates due to the potential for sensitive data exposure or disruption of business processes. The absence of authentication on a critical installer function could also facilitate supply chain attacks or unauthorized software modifications. Given that no user interaction or privileges are required, attackers could automate exploitation attempts, increasing the threat surface. However, the high attack complexity somewhat limits widespread exploitation. European organizations should consider the potential for targeted attacks, especially in sectors where SIGB PMB is integral to operations.
Mitigation Recommendations
1. Immediate upgrade to SIGB PMB version 8.0.1.2 or later, where the vulnerability is fixed. 2. Restrict network access to the installer component by implementing network segmentation and firewall rules to limit exposure only to trusted administrators or systems. 3. Employ application-layer gateways or web application firewalls (WAFs) that can detect and block anomalous installer requests. 4. Monitor logs and network traffic for unusual installer activity or unauthorized access attempts. 5. Implement strict access controls and multi-factor authentication for administrative interfaces related to SIGB PMB to reduce risk from other attack vectors. 6. Conduct regular vulnerability assessments and penetration testing focusing on SIGB PMB deployments to identify potential exploitation attempts. 7. Maintain an incident response plan that includes steps for rapid containment and remediation if exploitation is detected. These measures go beyond generic patching advice by emphasizing network-level controls, monitoring, and proactive security hygiene tailored to the nature of the vulnerability.
