CVE-2025-41669: CWE-347 Improper Verification of Cryptographic Signature in Phoenix Contact AXC F 1152
The Web-based Management allows a remote low privileged Engineer user to install additional APPs on the device downloaded from the PLCnext Store without implementing any data verification mechanism, leading to the capability for an Engineer user to reach arbitrary code execution with root privileges on the PLC device. A successful exploitation may allow to install a manipulated APP package, potentially impacting integrity and availability of the PLCnext Control.
AI Analysis
Technical Summary
The vulnerability CVE-2025-41669 in Phoenix Contact AXC F 1152 arises from improper verification of cryptographic signatures (CWE-347) in the Web-based Management interface. A remote low privileged Engineer user can install additional apps downloaded from the PLCnext Store without any data verification mechanism. This lack of signature validation allows an attacker with Engineer-level access to execute arbitrary code with root privileges by installing a manipulated app package. The vulnerability has a CVSS 4.0 score of 8.7, indicating high severity, with network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an Engineer user to execute arbitrary code with root privileges on the PLC device by installing manipulated app packages. This compromises the integrity and availability of the PLCnext Control system, potentially leading to unauthorized control or disruption of the device's operation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Engineer user privileges and limit access to the Web-based Management interface to trusted personnel only. Monitor for any unusual app installations or behavior on the device.
