An issue was discovered in PHOENIX CONTACT PC Worx through 1.86, PC Worx Express through 1.86, and Config+ through 1.86. A manipulated PC Worx or Config+ project file could lead to an Uninitialized Pointer and remote code execution. The attacker needs to get access to an original PC Worx or Config+ project file to be able to manipulate it. After manipulation, the attacker needs to exchange the original file with the manipulated one on the application programming workstation.
remediations
Vendor fix, mitigation, or workaround guidance, as published by each source.
A vendor fix is available.
- Fixedphoenix_contact_psirt
With the next version of Automationworx Software Suite the following measures will be implemented: The zlib component will be updated to the latest version (1.2.11.0). By utilizing the latest version of zlib a manipulated BCP file is detected as corrupt. The unpacking operation is aborted and therefor the remote code execution is precluded.\ The validation of input data will be improved.\ Objects in the affected software components will be completely initialized.\ Further 3rd party components will be checked for known vulnerabilities and will be exchanged or updated if required.\ General preventive security measures will be implemented such as address space layout randomization.
