Title: WvDial Insecure Default Permissions Vulnerability
Severity: MODERATE
Description:
WvDial is a Linux-based dialer, intended to allow dialup network functionality.
When WvDial is compiled and installed it creates a configuration file('wvdial.conf'). Sensitive information may be stored in this file, such as usernames/passwords for dialup services. The problem is that this file is created, by default, with world-readable permissions.
It should be noted that WvDial does not automatically store dialup account information. Additionally, users have the option of using a pre-existing configuration file.
Due to insecure default permissions, any local user on the host is privy to the information in this file.
It has been reported that this default configuration may not be present in all systems using WvDial (such as RedHat).
Affected Products:
- Worldvisions Computer Technology WvDial 1.4.1
- Worldvisions Computer Technology WvDial 1.4.2
