Description
A vulnerability was determined in zhistaredu StarTraining up to 3.8.1. This issue affects the function UserLoginService.createToken of the file application.yml of the component JWT Token Handler. This manipulation of the argument user_id/company_id causes use of hard-coded password. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in Zhistaredu StarTraining versions up to 3.8.1, specifically in the UserLoginService.createToken function within the application.yml file. This issue arises from the use of a hard-coded JWT secret, which allows for the creation of forged tokens by manipulating the user_id and company_id. The vulnerability can be exploited remotely, and the vendor has not responded to prior disclosure attempts.
To address this vulnerability, rotate the JWT secret to a secure value, add expiration and issued-at claims to the token, and remove any debug output that prints the secret or token.
