Vulnerability Details
The WordPress Picture / Portfolio / Media Gallery plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.0.1 via the 'file_get_contents' function. This vulnerability allows unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
The CVSS score of this vulnerability stands at 9.3, indicating a critical severity level. This high score highlights the potential for significant impact on confidentiality, integrity, and availability of affected systems. The CWE classification for this vulnerability is CWE-918, which pertains to Server-Side Request Forgery.
The vulnerability was published on June 19, 2024. Organizations using the affected plugin versions must act swiftly to protect their systems.
Technical Analysis
The root cause of this vulnerability is the improper handling of user input within the 'file_get_contents' function, which can lead to arbitrary web requests being made. The attack vector for this vulnerability is network-based, and the attack complexity is low, making it easier for attackers to exploit.
There are no privileges required for exploitation, and user interaction is not needed, which increases the vulnerability's risk profile. The confidentiality impact is high, as attackers may gain access to sensitive information. The integrity impact is low, indicating that while data could be queried, the ability to modify it may be limited. Availability impact is negligible, meaning that the service remains operational.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-5021 is significant. Organizations using the vulnerable plugin could face unauthorized access to internal services, leading to potential data breaches or unauthorized modifications of sensitive information. The blast radius is substantial, as many WordPress installations may be affected by this vulnerability.
Given the high CVSS score and the nature of the vulnerability, organizations should assess their exposure and prioritize mitigation efforts. The low exploitability score indicates a potential for exploitation, heightening the urgency for organizations to address this vulnerability in their patch cycle.
With an EPSS score of 0.007, the likelihood of exploitation in the wild is relatively low, but organizations should not become complacent. The risks associated with this vulnerability are substantial enough to warrant immediate attention and remediation.
