Summary

CVE-2024-57727 is a high-severity Path Traversal (CWE-22) vulnerability in Simple-Help Simplehelp. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

SimpleHelp remote support software versions 5.5.7 and earlier contain multiple path traversal vulnerabilities tracked as CVE-2024-57727. The flaws, assigned CWE-22, allow unauthenticated remote attackers to retrieve arbitrary files from the server by submitting specially crafted HTTP requests. Affected files include configuration data that stores secrets and hashed user passwords. The issue carries a CVSS 3.1 score of 7.5 with network attack vector, low complexity, and no required authentication or user interaction.

An attacker with network access to a SimpleHelp instance can directly exploit the path traversal conditions to exfiltrate sensitive server files. Successful exploitation yields configuration contents that may contain credentials or other material useful for further compromise of the host or connected systems.

Vendor guidance, research disclosures, and the CISA Known Exploited Vulnerabilities catalog address the issue, with the latter confirming observed exploitation in the wild. The associated EPSS score currently stands at 0.9405 with a recorded peak of 0.9413, indicating sustained and substantial exploitation interest following public disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
