CVE-2018-11235: In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2...

In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.

Security readout for executives and security teams

Plain-English summary

A malicious Git repository can run code on a developer or build machine when cloned with recursive submodules using vulnerable Git versions. This matters because source code checkouts often happen on trusted workstations and CI systems with valuable credentials.

Executive priority

Treat this as a high-priority engineering hygiene issue for build and developer infrastructure. It enables code execution through a routine source checkout path, but the provided evidence does not confirm active exploitation.

Technical view

Vulnerable Git versions trust submodule names from .gitmodules and append them under $GIT_DIR/modules. A crafted name can cause directory traversal and lead to execution of a submodule post-checkout hook during recursive clone, bypassing Git's intended protection against remote-supplied hooks.

Likely exposure

Exposure is most likely on developer workstations, CI runners, build servers, and automation that use affected Git versions and clone repositories with recursive submodules, especially from untrusted or externally contributed sources.

Exploitation context

The CVE source bundle includes an Exploit-DB reference, so public exploit material exists. The bundle does not show CISA KEV listing or cited evidence of active exploitation in the wild.

Researcher notes

The key exposure condition is vulnerable Git plus recursive submodule processing of a crafted repository. Focus validation on clone workflows, CI defaults, build containers, and developer tooling rather than internet-facing services alone.

Mitigation direction

  • Upgrade Git to the fixed version for each maintained release branch or vendor package.
  • Prioritize CI runners, build hosts, and developer endpoints that clone external repositories.
  • Avoid recursive submodule cloning from untrusted repositories until Git is patched.
  • Follow Red Hat, Ubuntu, Debian, Gentoo, SUSE, or upstream Git guidance for platform-specific packages.

Validation and detection

  • Inventory Git versions across developer endpoints, CI runners, and build images.
  • Confirm versions are at least 2.13.7, 2.14.4, 2.15.2, 2.16.4, or 2.17.1 as applicable.
  • Identify automation using recursive submodule cloning or submodule initialization.
  • Review source intake workflows for untrusted repositories or external pull-request build jobs.
  • Verify patched package versions against the relevant Linux distribution advisory.
