Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A critical security hole in Jenkins Git Plugin due to **missing authorization checks**.โฆ
๐ก๏ธ **Root Cause**: **Missing Authorization Check**. The plugin fails to verify if the user has permission to trigger specific build configurations.โฆ
๐ฆ **Affected**: **Jenkins Git Plugin**. ๐ **Version**: **4.11.3 and earlier**. ๐ข **Vendor**: Jenkins project. If you are running any version โค 4.11.3, you are vulnerable. โ ๏ธ
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: 1. Trigger builds of specific jobs. ๐โโ๏ธ 2. Specify a **malicious Git repository**. ๐ 3. Force checkout of an **attacker-specified commit**.โฆ
๐ **Exploitation Threshold**: **LOW**. The flaw is a missing check, meaning no complex bypass is needed. โก However, it requires the ability to trigger builds for jobs configured with Git.โฆ
๐ **Public Exploit**: **YES**. A Nuclei template exists: `CVE-2022-36883.yaml`. ๐ Found in `projectdiscovery/nuclei-templates`. ๐ Wild exploitation is possible using automated scanners. ๐ค
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: 1. Check Jenkins Plugin Manager for Git Plugin version. ๐ 2. Use Nuclei with the specific CVE template. ๐งช 3. Monitor build logs for unexpected Git repository URLs. ๐ 4.โฆ
๐ฉน **Official Fix**: **YES**. Jenkins issued a security advisory on **2022-07-27**. ๐ Update to a version **newer than 4.11.3**. ๐ The advisory link is available on jenkins.io/security. ๐
๐ฅ **Urgency**: **HIGH**. ๐จ Since it allows code execution via build hijacking, it's a critical risk. ๐ Patch immediately! โณ Delay increases the risk of data breach or system compromise. ๐๐จ
