Insufficiently Protected Credentials in Git - CVE-2020-11008

Published: April 23, 2020


Vulnerability identifier: #VU27257
CSH Severity: Low
CVSS v4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2020-11008
CWE-ID: CWE-522
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a remote attacker to gain access to sensitive information on the system

The vulnerability exists due to the Git can be tricked into sending private credentials to a host controlled by an attacker. A remote attacker can send a specially crafted URL to "git clone" that will present stored credentials for any host to a host of their choosing.

Note: This vulnerability is similar to the CVE-2020-5260 (SB2020041523). The fix for that bug still left the door open for an exploit where some credential is leaked (but the attacker cannot control which one).
