1. Jenkins is an open-source automation server targeted by threat actors for remote code execution. #Jenkins #vulnerability

2. The critical vulnerability, CVE-2024-23897, allows attackers to execute remote code through the CLI in Jenkins. #CVE-2024-23897 #remoteCodeExecution

3. Jenkins' default-enabled parser feature, 'expandAtFiles,' is responsible for the vulnerability. #expandAtFiles #securityvulnerability

4. Attackers can access the file system through the args4j library, compromising the system's security. #args4j #fileSystemAccess

5. Reading binary files with cryptographic keys is possible with restrictions, leading to potential RCE attacks. #RCE #cryptographicKeys

6. The vulnerability enables remote code execution via different methods such as resource root URLs and build logs. #remoteCodeExecution #buildLogs

7. Jenkins has fixed the vulnerability in version 2.442/LTS 2.426.3 but provides a temporary CLI access block as a workaround. #vulnerabilityFix #tempAccessBlock

8. Other vulnerabilities, CVE-2024-23898, CVE-2024-23899, CVE-2023-6148, CVE-2024-23905, CVE-2024-23904, and CVE-2023-6147, have also been detected. #otherVulnerabilities
