CVE-2024-56320
CVE-2024-56320 allows for admin privilege escalation in GoCD servers. This vulnerability stems from improper authorization when accessing the admin "Configuration XML" UI feature and API in GoCD versions prior to 24.5.0. An authenticated user can exploit this to gain unauthorized access or escalate their privileges.
Despite a CVSS score of 0, the SOCRadar Vulnerability Risk Score (SVRS) is 30, highlighting a potential risk even though the CVSS score is very low. This means, although the impact and exploitability may seem low when calculating the CVSS, SOCRadar's analysis of threat actor activity and mentions in sources such as social media and dark web sources suggests this could be a risk. Upgrading to GoCD 24.5.0 is highly recommended. If immediate upgrade isn't feasible, consider using a reverse proxy to block access to /go/rails/ paths as a mitigation measure. The vulnerability poses a significant risk if left unpatched.
Description
CVE-2024-56320 affects GoCD, a continuous delivery server, and allows for admin privilege escalation in versions prior to 24.5.0. This vulnerability stems from improper authorization of access to the admin "Configuration XML" UI feature and its associated API. This allows a malicious insider or authenticated GoCD user to exploit the vulnerability and potentially gain unauthorized access to sensitive information or escalate their privileges to that of a GoCD administrator.
SVRS: The vulnerability has an SVRS of 30, indicating a moderate risk level. While the CVSS is 0, the SVRS score highlights the potential for significant impact, particularly considering the potential for privilege escalation and access to sensitive data.
Key Insights
- Privilege Escalation: This vulnerability allows an authenticated GoCD user to escalate their privileges to that of a GoCD administrator. This grants them access to sensitive configuration information and potentially control over the GoCD server.
- Insider Threat: The vulnerability is particularly concerning as it can be exploited by malicious insiders with existing GoCD user accounts. This emphasizes the importance of strong access control measures and user vetting.
- Persistent Impact: The exploitation of this vulnerability can result in persistent access for the attacker, allowing them to maintain control over the GoCD server and potentially disrupt its operations.
Mitigation Strategies
- Upgrade to GoCD 24.5.0 or later: This is the most effective mitigation strategy as it addresses the vulnerability directly.
- Implement Access Control Measures: Restrict access to the GoCD server by limiting the number of users with administrative privileges. Implement strong password policies and multi-factor authentication to further enhance security.
- Block Access to the Vulnerable Route: Consider using a reverse proxy, WAF, or similar technologies to block access to the vulnerable route with a
/go/rails/prefix. This will prevent exploitation of the vulnerability, but it may require careful configuration to avoid impacting legitimate functionality. - Limit Plugin Usage: Temporarily disable plugins like the guest-login-plugin that grant limited anonymous access, reducing the potential for attackers to exploit this vulnerability.
