Описание

A vulnerability was detected in antlr ANTLR4 up to 4.13.2. Affected by this issue is the function getImportedVocabFile of the file tool/src/org/antlr/v4/parse/TokenVocabParser.java of the component tokenVocab Grammar Option Handler. The manipulation results in path traversal. The attack can be executed remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A flaw was found in antlr ANTLR4. A remote attacker can exploit a path traversal vulnerability by manipulating the getImportedVocabFile function within the tokenVocab Grammar Option Handler component. This could allow unauthorized access to sensitive files and directories on the system.

Отчет

Successful exploitation requires a specific scenario where an application using ANTLR4 is configured to accept and parse untrusted, attacker-supplied grammar files containing a manipulated tokenVocab option. Impact Limitations: The vulnerability is strictly limited to information disclosure via path traversal. While a remote attacker can read sensitive files that the application has permissions to access, this flaw does not inherently allow for remote code execution (RCE), data corruption, or privilege escalation on the host system.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
