CVE-2026-26514 Details
Description
An Argument Injection vulnerability exists in bird-lg-go before commit 6187a4e. The traceroute module uses shlex.Split to parse user input without validation, allowing remote attackers to inject arbitrary flags (e.g., -w, -q) via the q parameter. This can be exploited to cause a Denial of Service (DoS) by exhausting system resources.
A vulnerability allowing argument injection has been identified in the bird-lg-go project, prior to commit 6187a4e. The issue arises in the traceroute module, which improperly parses user input using shlex.Split without validation. This flaw enables remote attackers to inject arbitrary flags, such as -w and -q, through the q parameter. Exploitation of this vulnerability can lead to a denial-of-service condition by exhausting system resources.
Users are advised to update to the latest version of bird-lg-go, where this vulnerability has been addressed.
