Vulnerability Details
A vulnerability, which was classified as critical, has been found in DouPHP 1.7 Release 20220822. Affected by this issue is some unknown functionality of the file /admin/system.php of the component Favicon Handler. The manipulation of the argument site_favicon leads to unrestricted upload. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.
This vulnerability falls under the CWE-434 classification, which relates to the unrestricted upload of files. Given its CVSS score of 5.1, it is important for organizations to assess their exposure and potential impacts.
Technical Analysis
The root cause of this vulnerability is the lack of adequate validation on file uploads in the Favicon Handler component of DouPHP. Attackers may leverage this vulnerability by sending crafted requests to manipulate the site_favicon argument, enabling them to upload arbitrary files to the server.
The attack vector is classified as network-based, which means that attackers can exploit this vulnerability from a remote location without requiring physical access to the affected system. The attack complexity is low, and it requires high privileges to execute the attack successfully.
User interaction is not required for the exploitation of this vulnerability. The potential impacts on confidentiality, integrity, and availability are considered low, but the unrestricted upload could lead to significant security risks if exploited.
Risk & Impact Analysis
Risk to organizations includes the potential for attackers to upload malicious files, which could lead to further compromises or unauthorized data access. The blast radius may vary depending on the deployment environment and the privileges of the compromised user account.
Given the CVSS score of 5.1, organizations should address this vulnerability in their priority patch cycle. The existence of public knowledge around this vulnerability increases the urgency for remediation.
