Gogs vulnerable to improper PAM authorization handling
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | gogs.io/gogs | < 0.12.5 | 0.12.5 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Expired PAM accounts and accounts with expired passwords are continued to be seen as valid. Installations use PAM as authentication sources are affected.
### Patches
Expired PAM accounts and accounts with expired passwords are no longer being seen as valid. Users should upgrade to 0.12.5 or the latest 0.13.0+dev.
### Workarounds
In addition to marking PAM accounts as expired, also disable/lock them. Running `usermod -L <username>` will add an exclamation mark to the password hash and would result in wrong passwords responses when trying to login.
