CVE-2022-3483: 
GitLab vulnerability analysis and mitigation

CVE-2022-3483 is a security vulnerability discovered in GitLab CE/EE affecting all versions starting from 12.1 before 15.3.5, all versions starting from 15.4 before 15.4.4, and all versions starting from 15.5 before 15.5.2. The vulnerability was related to the Datadog integration functionality where maintainers could potentially expose sensitive API keys (GitLab Security Release).

The vulnerability stems from incomplete fixes for previous CVEs (CVE-2022-2497 and CVE-2022-2882) in GitLab's Datadog integration. The issue allowed a malicious maintainer to exfiltrate a Datadog integration's access token by modifying the integration URL to send authenticated requests to an attacker-controlled server. The vulnerability was assigned a CVSS score of 5.5 (Medium) with the vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N (GitLab Security Release).

The vulnerability could allow malicious maintainers to leak Datadog API keys and subsequently modify or exfiltrate information on Datadog. This exposure of sensitive credentials could potentially lead to unauthorized access to monitoring and analytics data (GitLab Security Release).

The vulnerability was patched in GitLab versions 15.3.5, 15.4.4, and 15.5.2. The fix involved adding proper validation for exposing secrets in the Datadog integration model. Users are strongly recommended to upgrade to these or later versions to mitigate the vulnerability (GitLab Security Release).

The vulnerability was responsibly disclosed through GitLab's HackerOne bug bounty program by security researcher ryotak. GitLab addressed the vulnerability promptly and included it in their security release along with several other security fixes (GitLab Security Release).
