Cobham · Cobham Satcom Sailor 500 · CVE-2018-19392
**Name of the Vulnerable Software and Affected Versions**
Cobham Satcom Sailor 250 and 500 devices versions prior to 1.25
**Description**
The issue allows for an unauthenticated password reset, enabling modification of any user account's password, including the default "admin" account, without prior knowledge of the password. This can be achieved with knowledge of the username and by exploiting the attack vector through the "/index.lua" API endpoint, specifically the `usernameAdmChange`, `passwordAdmChange1`, and `passwordAdmChange2` fields.
**Recommendations**
For versions prior to 1.25, update to version 1.25 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/index.lua" API endpoint, particularly the `usernameAdmChange`, `passwordAdmChange1`, and `passwordAdmChange2` fields, to minimize the risk of exploitation.
