01

What, why and how

GitLab Community and Enterprise Editions contain an improper access control vulnerability. This allows an attacker to trigger password reset emails to be sent to an unverified email address to ultimately facilitate an account takeover.

What

GitLab Community and Enterprise Editions contain an improper access control vulnerability. This allows an attacker to trigger password reset emails to be sent to an unverified email address to ultimately facilitate an account takeover.

Why

The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may bypass an access boundary or take over an account.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2024-05-01.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path
a network path → Weak Password Recovery Mechanism for Forgotten Password → bypass an access boundary or take over an account

CWE-640

CWE-640: Weak Password Recovery Mechanism for Forgotten Password. The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
