CVE-2022-32417 is a critical remote code execution (RCE) vulnerability identified in PbootCMS version 3.1.2. This vulnerability allows attackers to execute arbitrary code through the function parserIfLabel located in the function.php file. With a CVSS score of 9.8, it poses a significant threat to systems utilizing this content management system.
The vulnerability has a high potential for exploitation, given its low attack complexity and the lack of required privileges or user interaction. As a result, organizations using PbootCMS are advised to prioritize the implementation of patches as soon as they become available to protect against potential attacks.
Risk to organizations includes unauthorized access and control over affected systems, which could lead to data breaches or service disruptions. Therefore, organizations should prioritize patching immediately.
At this time, there are no known public exploits or proof of concept available for this vulnerability, but the potential for exploitation remains high. Organizations should remain vigilant and ensure their systems are up to date.
Vulnerability Details
The official description for CVE-2022-32417 states: PbootCMS v3.1.2 was discovered to contain a remote code execution (RCE) vulnerability via the function parserIfLabel at function.php.
This vulnerability is classified under CWE-94 (Improper Control of Generation of Code). It is critical due to its high CVSS score of 9.8, indicating a severe level of risk. Organizations using this version of PbootCMS should take immediate action to secure their systems.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of input within the function parserIfLabel. This function's logic can be manipulated by attackers to execute arbitrary code on the server, which can lead to complete system compromise. The attack vector for this vulnerability is network-based, allowing attackers to exploit it remotely with minimal effort.
The attack complexity is low, as no special privileges are needed, and user interaction is not required. The confidentiality, integrity, and availability impacts are all rated as high, meaning that successful exploitation could lead to the exposure of sensitive data, unauthorized data modification, and system outages.
Risk & Impact Analysis
The real-world risk of this vulnerability is substantial. If attackers successfully exploit this vulnerability, they could gain complete control over the affected systems, leading to significant data breaches and operational disruptions. The blast radius is particularly concerning, as many organizations deploy PbootCMS in environments containing sensitive customer data or critical business operations.
Furthermore, with an EPSS score of 0.4267, this vulnerability falls into a high-risk category, indicating a significant probability of exploitation. Thus, organizations should address this vulnerability in their priority patch cycle.
