This security advisory describes one low risk vulnerability.

1) Insufficiently Protected Credentials

Severity: Low

3.5 [CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]


CWE-522 – Insufficiently Protected Credentials

Exploit availability:


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).
