CVE-2023-23618

Estado: ModificadaAlta (7.8)—

Git for Windows is the Windows port of the revision control system Git. Prior to Git for Windows version 2.39.2, when `gitk` is run on Windows, it potentially runs executables from the current directory inadvertently, which can be exploited with some social engineering to trick users into running untrusted code. A patch is available in version 2.39.2. As a workaround, avoid using `gitk` (or Git GUI's "Visualize History" functionality) in clones of untrusted repositories.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
