A vulnerability was identified in Pagekit up to version 1.0.18. This vulnerability allows the manipulation of the argument url in the file /index.php/admin/system/update/download, leading to server-side request forgery. Since the exploit is publicly available, remote exploitation of the attack is possible. Organizations should take note that the vendor was contacted early regarding this disclosure but did not respond.
The CVSS score for this vulnerability is 5.1, which classifies it as medium severity. The urgency for defenders to act is medium as well, considering the potential risks associated with this vulnerability.
Risk to organizations includes the potential for unauthorized access and data exposure. Given the nature of server-side request forgery, attackers may leverage this vulnerability to perform actions on behalf of the server, which could lead to further exploitation of the affected system.
Organizations should prioritize patching this vulnerability immediately to mitigate potential risks.
Vulnerability Details
The vulnerability identified in Pagekit up to version 1.0.18 allows for server-side request forgery through the manipulation of the url argument in the specified file. The attack vector is network-based with low attack complexity. It requires high privileges to exploit, and there is no user interaction required.
The CVSS base score for this vulnerability is 5.1, indicating a medium severity level. The confidentiality, integrity, and availability impacts are all classified as low.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user-supplied input within the application. Specifically, the system does not adequately validate or sanitize the url parameter, allowing attackers to craft malicious requests.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability from any location with network access to the target system. The attack complexity is low, as it does not require advanced techniques to exploit.
Given that high privileges are required to exploit this vulnerability, it is critical for organizations to restrict access to sensitive functionalities and apply the principle of least privilege to minimize the risks associated with potential exploitation.
Risk & Impact Analysis
Real-world deployment risk is significant due to the public availability of the exploit. Attackers may leverage this vulnerability to perform unauthorized actions, leading to data breaches or further system compromises.
Organizations must understand that the blast radius of this vulnerability could extend beyond the immediate system, affecting connected systems and data integrity.
The urgency assessment based on the CVSS score and the potential for exploitation indicates that organizations should address this vulnerability in their priority patch cycle.
