Title: rPath Linux Initscripts /VAR/LOG/BTMP File Local Information Disclosure Vulnerability
Severity: LOW
Description:
rPath Linux is a specialized GNU/Linux distribution for enterprise users. The 'initscripts' package is used when initializing and shutting down the system.
rPath Linux is prone to a local information-disclosure vulnerability because scripts from the 'initscripts' package fail to set file permissions correctly on the '/var/log/btmp' file.
Specifically, the '/var/log/btmp' file permissions are set to 664 (-rw-rw-r--) instead of 660 (-rw-rw----), which gives all users read access to the file. This may potentially disclose user passwords from unsuccessful login attempts because the '/var/log/btmp' file keeps a log of usernames from failed logins. When a user accidentally enters a password in the username field, this password will be logged.
This issue occurs only when users fail to log in at the system text console or over a local serial port.
Attackers can leverage this issue to obtain valuable information to construct valid login credentials.
This issue affects rPath Linux 1; other versions may also be affected.
Affected Products:
- Foresight Linux Foresight Linux 1.1
- rPath rPath Linux 1
