In affected versions when unpacking Tar archives, Gradle did not check that files could be written outside of the unpack location. This could lead to important files being overwritten anywhere the Gradle process has write permissions. For a build reading Tar entries from a Tar archive, this issue could allow Gradle to disclose information from sensitive files through an arbitrary file read. To exploit this behavior, an attacker needs to either control the source of an archive already used by the build or modify the build to interact with a malicious archive. It is unlikely that this would go unnoticed. A fix has been released in Gradle 7.6.2 and 8.2 to protect against this vulnerability. Starting from these versions, Gradle will refuse to handle Tar archives which contain path traversal elements in a Tar entry name. Users are advised to upgrade. There are no known workarounds for this vulnerability. ### Impact This is a path traversal vulnerability when Gradle deals with Tar archives, often referenced as TarSlip, a variant of ZipSlip. * When unpacking Tar archives, Gradle did not check that files could be written outside of the unpack location. This could lead to important files being overwritten anywhere the Gradle process has write permissions. * For a build reading Tar entries from a Tar archive, this issue could allow Gradle to disclose information from sensitive files through an arbitrary file read. To exploit this behavior, an attacker needs to either control the source of an archive already used by the build or modify the build to interact with a malicious archive. It is unlikely that this would go unnoticed. Gradle uses Tar archives for its [Build Cache](https://docs.gradle.org/current/userguide/build_cache.html). These archives are safe when created by Gradle. But if an attacker had control of a remote build cache server, they could inject malicious build cache entries that leverage this vulnerability. This attack vector could also be exploited if a man-in-the-middle can be performed between the remote cache and the build. ### Patches A fix has been released in Gradle 7.6.2 and 8.2 to protect against this vulnerability. Starting from these versions, Gradle will refuse to handle Tar archives which contain path traversal elements in a Tar entry name. It is recommended that users upgrade to a patched version. ### Workarounds There is no workaround. * If your build deals with Tar archives that you do not fully trust, you need to inspect them to confirm they do not attempt to leverage this vulnerability. * If you use the Gradle remote build cache, make sure only trusted parties have write access to it and that connections to the remote cache are properly secured. ### References * [CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')](https://cwe.mitre.org/data/definitions/22.html) * [Gradle Build Cache](https://docs.gradle.org/current/userguide/build_cache.html) * [ZipSlip](https://security.snyk.io/research/zip-slip-vulnerability) CVE-2023-35947 SUSE Enterprise Storage 7.1:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise High Performance Computing 15 SP2-LTSS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise High Performance Computing 15 SP3-LTSS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise High Performance Computing 15 SP4-ESPOS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise High Performance Computing 15 SP4-LTSS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Module for Development Tools 15 SP5:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Module for Development Tools 15 SP6:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Server 15 SP2-LTSS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Server 15 SP3-LTSS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Server 15 SP4-LTSS:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Server for SAP Applications 15 SP2:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Server for SAP Applications 15 SP3:gradle-4.4.1-150200.3.27.1 SUSE Linux Enterprise Server for SAP Applications 15 SP4:gradle-4.4.1-150200.3.27.1 openSUSE Leap 15.5:gradle-4.4.1-150200.3.27.1 openSUSE Leap 15.6:gradle-4.4.1-150200.3.27.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2024/suse-su-20243923-1/ https://www.suse.com/security/cve/CVE-2023-35947.html CVE-2023-35947 https://bugzilla.suse.com/1212931 SUSE Bug 1212931
