CVE-2023-26918
Filereplicationpro File Replication Pro 7.5.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-26918 is a critical-severity Incorrect Default Permissions (CWE-276) vulnerability in Filereplicationpro File Replication Pro. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Services File Permissions Weakness (T1574.010); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Access control policy can specify and enforce secure default permissions for resources.
Guides setting of default permissions to the minimum required level.
Establishes requirements for appropriate default permissions on system resources as part of configuration management.
Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.
Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.
Requires documented processes that include setting and maintaining correct default permissions for configuration items.
Requires addressing secure default permissions in physical and environmental protection controls.
Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.
Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.
Hardened baselines and configuration management explicitly require correct default file permissions.
Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.
