AXC F 1152: Improper Link Resolution Before File Access
CVE-2025-41667 is a high-severity improper link resolution before file access vulnerability in AXC F 1152 from Phoenix Contact, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 2025.0.2 as the first without the flaw, so updating AXC F 1152 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.62% chance of exploitation within 30 days, higher than 50% of scored CVEs.
High severity with no evidence of exploitation so far.

Official description
A low privileged remote attacker with file access can replace a critical file used by the arp-preinit script to get read, write and execute access to any file on the device.

The underlying weakness: Improper Link Resolution Before File Access
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
How developers prevent this class of flaw
- Follow the principle of least privilege when assigning access rights to entities in a software system. Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
