CVE-2024-57727

CVE-2024-57727 consists of multiple path traversal vulnerabilities (CWE-22) in SimpleHelp remote support/remote access software that affect versions 5.5.7 and earlier. Because affected request handlers do not properly validate file paths, an unauthenticated remote attacker can send crafted HTTP requests to traverse directories and download arbitrary files from the SimpleHelp server host. The attacker gains access to sensitive server configuration files containing secrets and hashed user passwords, which can support follow-on attacks such as offline password cracking and deeper compromise; ransomware operators have chained SimpleHelp flaws in double-extortion attacks, including against an MSP and its downstream customers. Any organization running SimpleHelp is affected, particularly internet-facing deployments and MSPs that use the product for remote support and access. Exploitation is confirmed in the wild: CISA added the flaw to the KEV on 2025-02-13 with known ransomware use, EPSS assigns a 95.2% probability of exploitation within 30 days, and reporting links exploitation to campaigns such as a DragonForce operator targeting an MSP and its customers and Storm-1175 ransomware activity.

What to do: Upgrade all SimpleHelp servers to a patched release newer than 5.5.7 per the vendor's instructions, or apply vendor-recommended mitigations or discontinue use if patching is unavailable (the CISA KEV required action). Since the flaw exposes configuration files and hashed user passwords, rotate embedded secrets and force credential/password resets, and review SimpleHost/server access logs for unauthenticated traversal-style download requests. MSPs should check their SimpleHelp server for signs of compromise, as ransomware operators have chained these flaws to reach downstream customers.
