An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
- CVE-2021-21685
Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not check agent-to-controller access to create parent directories in FilePath#mkdirs.
UpstreamEPSS 1.5% - CVE-2021-21686
File path filters in the agent-to-controller security subsystem of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories.
UpstreamEPSS 1.9% - CVE-2021-21687
Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not check agent-to-controller access to create symbolic links when unarchiving a symbolic link in FilePath#untar.
UpstreamEPSS 1.3% - CVE-2021-21688
The agent-to-controller security check FilePath#reading(FileVisitor) in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not reject any operations, allowing users to have unrestricted read access using certain operations (creating archives, FilePath#copyRecursiveTo).
UpstreamEPSS 1.3% - CVE-2021-21689
FilePath#unzip and FilePath#untar were not subject to any agent-to-controller access control in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
UpstreamEPSS 1.4% - CVE-2021-21690
Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
UpstreamEPSS 2.5% - CVE-2021-21691
Creating symbolic links is possible without the 'symlink' agent-to-controller access control permission in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
UpstreamEPSS 2.0% - CVE-2021-21692
FilePath#renameTo and FilePath#moveAllChildrenTo in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier only check 'read' agent-to-controller access permission on the source path, instead of 'delete'.
UpstreamEPSS 2.0% - CVE-2021-21693
When creating temporary files, agent-to-controller access to create those files is only checked after they've been created in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
UpstreamEPSS 1.5% - CVE-2021-21694
FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
UpstreamEPSS 1.5% - CVE-2021-21695
FilePath#listFiles lists files outside directories that agents are allowed to access when following symbolic links in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.
UpstreamEPSS 2.1% - CVE-2021-21696
Jenkins 2.318 and earlier, LTS 2.303.2 and earlier does not limit agent read/write access to the libs/ directory inside build directories when using the FilePath APIs, allowing attackers in control of agent processes to replace the code of a trusted library with a modified variant. This results in unsandboxed code execution in the Jenkins controller process.
UpstreamEPSS 2.3% - CVE-2021-21697
Jenkins 2.318 and earlier, LTS 2.303.2 and earlier allows any agent to read and write the contents of any build directory stored in Jenkins with very few restrictions.
UpstreamEPSS 1.6% - CVE-2021-21698
Jenkins Subversion Plugin 2.15.0 and earlier does not restrict the name of a file when looking up a subversion key file on the controller from an agent.
