On May 26, 2023, a critical Server-Side Template Injection (SSTI) vulnerability was discovered in Tuzitio's Camaleon CMS version 2.7.0. This vulnerability is classified with a CVSS score of 9.8, indicating a severe risk to organizations utilizing this software. The vulnerability was identified via the formats parameter, which can be manipulated to execute arbitrary code on the server.
Risk to organizations includes potential unauthorized access to sensitive information, disruption of service, and integrity compromises. As the attack vector is network-based and requires no user interaction, the urgency for remediation is high. Organizations should prioritize patching immediately.
Current exploitation status indicates that there is at least one confirmed exploit available, making it critical for affected users to assess their environments and apply necessary updates to mitigate risks.
Organizations leveraging Camaleon CMS should not only implement the latest patches but also review their security posture and enhance monitoring strategies to detect any potential misuse of this vulnerability.
Vulnerability Details
The vulnerability identified as CVE-2023-30145 allows for Server-Side Template Injection (SSTI) due to improper validation of user input in the formats parameter. The CVSS score of 9.8 categorizes this vulnerability as critical, affecting confidentiality, integrity, and availability. The affected product is Camaleon CMS v2.7.0, published on May 26, 2023, with a weakness categorized under CWE-94.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper input validation, allowing attackers to inject malicious templates that can lead to remote code execution. The attack vector is network-based, requiring no special privileges or user interaction, with low complexity for exploitation.
Given the high confidentiality, integrity, and availability impacts associated with this vulnerability, organizations must take this threat seriously. The absence of required privileges and the low complexity of attacks make this vulnerability particularly dangerous.
Risk & Impact Analysis
The potential blast radius of this vulnerability is extensive, given the widespread use of Camaleon CMS. Attackers may leverage this vulnerability to access sensitive data, alter system functionality, or disrupt services. Organizations should assess their exposure and deploy necessary patches and mitigations.
Based on the CVSS score and the confirmed exploit, organizations must prioritize this vulnerability in their patch management processes to prevent potential breaches or service disruptions.
