CVE-2022-42968: n/a in n/a
Gitea before 1.17.3 does not sanitize and escape refs in the git backend. Arguments to git commands are mishandled.
AI Analysis
Technical Summary
CVE-2022-42968 is a critical security vulnerability affecting Gitea versions prior to 1.17.3. Gitea is a popular open-source, self-hosted Git service used for source code management and collaboration. The vulnerability arises because Gitea does not properly sanitize and escape references (refs) in its Git backend. Specifically, arguments passed to Git commands are mishandled, leading to the possibility of command injection or arbitrary command execution. This vulnerability is classified under CWE-88 (Improper Neutralization of Argument Delimiters in a Command), indicating that malicious input can manipulate command arguments to execute unintended commands. The CVSS v3.1 base score is 9.8, reflecting a critical severity level due to the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this flaw could allow an unauthenticated attacker to execute arbitrary commands on the server hosting Gitea, potentially leading to full system compromise, data theft, or disruption of services. Although no known exploits in the wild have been reported, the high severity and ease of exploitation make this a significant threat for organizations relying on vulnerable Gitea instances. The lack of vendor or product details in the provided information is likely due to Gitea being a community-driven project rather than a commercial vendor. The vulnerability was published on October 16, 2022, and a patched version (1.17.3) is available to remediate the issue.
Potential Impact
For European organizations, the impact of this vulnerability can be substantial, especially for those using Gitea as part of their software development lifecycle. Compromise of a Gitea server could lead to unauthorized access to source code repositories, exposing intellectual property and sensitive business logic. Attackers could inject malicious code into repositories, potentially affecting downstream software builds and deployments. Additionally, the ability to execute arbitrary commands on the server could allow attackers to pivot within the network, escalate privileges, or disrupt development operations by deleting or altering repositories. This could result in significant operational downtime, loss of trust, and regulatory compliance issues, particularly under GDPR if personal data is stored or processed within the compromised environment. The critical nature of the vulnerability means that even organizations with robust perimeter defenses are at risk if their Gitea instances are exposed to the internet or accessible internally without adequate segmentation and monitoring.
Mitigation Recommendations
European organizations should immediately upgrade all Gitea instances to version 1.17.3 or later, where this vulnerability has been patched. If upgrading is not immediately feasible, organizations should restrict network access to Gitea servers, limiting exposure to trusted internal networks only. Implement strict input validation and sanitization on any custom integrations or plugins interacting with Git refs. Employ network segmentation and firewall rules to isolate Gitea servers from critical infrastructure. Enable comprehensive logging and monitoring to detect suspicious command execution or unusual repository activity. Regularly audit repository contents and access logs for signs of tampering. Additionally, consider deploying runtime application self-protection (RASP) or host-based intrusion detection systems (HIDS) on Gitea hosts to detect and prevent exploitation attempts. Finally, ensure incident response plans include scenarios for source code repository compromise to enable rapid containment and recovery.
