Detailsinfo

A vulnerability classified as critical has been found in radare2 up to 4.4.x (Programming Tool Software). Affected is some unknown functionality of the component PDB File Name Handler. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In radare2 before version 4.5.0, malformed PDB file names in the PDB server path cause shell injection. To trigger the problem it's required to open the executable in radare2 and run idpd to trigger the download. The shell code will execute, and will create a file called pwned in the current directory.

The weakness was disclosed 07/20/2020 (GitHub Repository). The advisory is shared for download at github.com. This vulnerability is traded as CVE-2020-15121 since 06/25/2020.
