CVE-2024-57727
Published: 15 January 2025
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 File and Directory Discovery (T1083); 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
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.
