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.

Vulnerability Data

Diasoft File Replication Pro 7.5.0 allows attackers to escalate privileges by replacing a legitimate file with a Trojan horse that will be executed as LocalSystem. This occurs because %ProgramFiles%\FileReplicationPro allows Everyone:(F) access.

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.

addresses: CWE-276

Access control policy can specify and enforce secure default permissions for resources.

addresses: CWE-276

Guides setting of default permissions to the minimum required level.

addresses: CWE-276

Establishes requirements for appropriate default permissions on system resources as part of configuration management.

addresses: CWE-276

Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.

addresses: CWE-276

Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.

addresses: CWE-276

Requires documented processes that include setting and maintaining correct default permissions for configuration items.

addresses: CWE-276

Requires addressing secure default permissions in physical and environmental protection controls.

addresses: CWE-276

Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.

PR.PS-01 full match
prevents

Hardened baselines and configuration management explicitly require correct default file permissions.

PR.AA-05 mostly match
prevents

Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.

ID.AM-08 partial match
prevents

Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.

PR.PS-06 partial match
prevents

Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
