Deeper analysis

Diasoft File Replication Pro 7.5.0 is affected by an insecure permissions vulnerability in the directory %ProgramFiles%\FileReplicationPro, which grants Everyone:(F) access and thereby allows replacement of legitimate binaries with attacker-controlled files. The flaw is tracked as CWE-276 and carries a CVSS 3.1 score of 9.8, reflecting network-exploitable privilege escalation to LocalSystem.

An unauthenticated attacker can upload or copy a Trojan horse into the directory and have it executed with LocalSystem rights during normal service operation, resulting in full control of the host. Exploitation requires only the ability to write to the affected path, which is possible remotely given the Everyone full-control ACL.

The EPSS score rose from a low baseline to a recorded peak of 0.0958 before settling at 0.0717, indicating measurable post-disclosure interest in the issue. Public references consist of an exploit posting on Packet Storm and the vendor site, with no vendor advisory or patch information supplied in the available references.
