CVE-2024-57728 describes a high-severity vulnerability in SimpleHelp remote support software, specifically versions 5.5.7 and earlier. This vulnerability allows admin users to upload arbitrary files anywhere on the file system by uploading a crafted zip file, commonly referred to as a zip slip. The implications of this vulnerability are significant, as it can be exploited to execute arbitrary code on the host in the context of the SimpleHelp server user. With a CVSS score of 7.2, this vulnerability poses serious risks to organizations utilizing the affected software.
The risk to organizations includes unauthorized access to sensitive data and potential system compromise. Given the high attack vector score and low complexity required for exploitation, organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. No known public exploits are currently available, but the nature of the vulnerability means that it could be exploited in the wild.
The SimpleHelp vulnerability was published on January 15, 2025, and has since been marked as modified. Organizations using this software are strongly advised to remain vigilant and ensure they implement the necessary updates as soon as possible to safeguard against potential attacks.
In summary, the urgency for defenders is clear: update to the latest version of SimpleHelp as soon as possible to address this critical vulnerability.
Vulnerability Details
The vulnerability detailed in CVE-2024-57728 affects SimpleHelp remote support software versions up to 5.5.7. It allows admin users to upload crafted zip files to any location in the file system, hence executing arbitrary code under the SimpleHelp server user context. The CVSS 3.1 score of 7.2 classifies this vulnerability as high severity, emphasizing the impact on confidentiality, integrity, and availability. The vulnerability is associated with CWE-59 and CWE-22, indicating issues related to the improper restriction of operations within the bounds of a memory buffer and path traversal, respectively.
Technical Analysis
The root cause of this vulnerability is the inadequate validation of zip file uploads, allowing for path traversal attacks. The attack vector is classified as network-based, which means that an attacker can exploit this vulnerability remotely without needing physical access to the device. The attack complexity is low, and the privileges required are high, meaning that an attacker must have administrative access to exploit this vulnerability. No user interaction is required, which further increases the risk. The impact on confidentiality, integrity, and availability is deemed high due to the potential for unauthorized access and system compromise.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant. Organizations using SimpleHelp must be aware that the failure to address this vulnerability can lead to severe consequences, including unauthorized access to sensitive data and potential data breaches. The blast radius for this vulnerability can be extensive, especially for organizations with large networks or those that use SimpleHelp extensively for remote support. Given the high CVSS score and the current lack of known exploits, organizations should schedule remediation as part of their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The versions affected by this vulnerability include all versions of SimpleHelp prior to 5.5.8. Organizations should ensure they are running the latest version to mitigate this risk.
Mitigation & Remediation
To mitigate the risk associated with CVE-2024-57728, organizations should upgrade to SimpleHelp version 5.5.8 or later as soon as possible. If upgrading is not immediately feasible, organizations can implement temporary workarounds such as restricting file upload capabilities for admin users or monitoring file uploads for suspicious activity.
