Use of a Key Past its Expiration Date and Insufficient Session Expiration in Maddy Mail Server
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | github.com/foxcpp/maddy | < 0.5.4 | 0.5.4 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Any configuration on any maddy version <0.5.4 using auth.pam is affected.
No password expiry or account expiry checking is done when authenticating using PAM.
### Patches
Patch is available as part of the 0.5.4 release.
### Workarounds
If /etc/shadow authentication is used, it is possible to replace auth.pam with auth.shadow which is not affected.
It is possible to blacklist expired accounts via existing filtering mechanisms (e.g. auth_map to invalid accounts in storage.imapsql).
