Summaryinfo

A vulnerability, which was classified as critical, was found in GNU Emacs up to 30.0.92. The impacted element is an unknown function of the file elisp-mode.el. The manipulation results in code injection. This vulnerability is known as CVE-2024-53920. No exploit is available.

Detailsinfo

A vulnerability was found in GNU Emacs up to 30.0.92. It has been classified as critical. Affected is some unknown functionality of the file elisp-mode.el. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In elisp-mode.el in GNU Emacs through 30.0.92, a user who chooses to invoke elisp-completion-at-point (for code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.)

The advisory is shared for download at git.savannah.gnu.org. This vulnerability is traded as CVE-2024-53920 since 11/25/2024. The exploitability is told to be easy. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1059.

The vulnerability scanner Nessus provides a plugin with the ID 213301 (SUSE SLED15 / SLES15 / openSUSE 15 Security Update : emacs (SUSE-SU-2024:4392-1)), which helps to determine the existence of the flaw in a target environment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Tenable (213301), EUVD (EUVD-2024-52189) and CERT Bund (WID-SEC-2025-1905). Once again VulDB remains the best source for vulnerability data.
