CVE-2024-53484 is a vulnerability in Ever Traduora versions 0.20.0 and below caused by the use of a hard-coded JSON Web Token (JWT) signing key. JWTs are commonly used for authentication and authorization in web applications. The hard-coded key means that the signing secret is embedded directly in the application code and is the same across all installations. This allows an attacker with some level of access (low privileges) to generate or forge valid JWTs, thereby escalating their privileges within the application. The vulnerability is classified under CWE-798 (Use of Hard-coded Credentials), which is a well-known security anti-pattern. The CVSS v3.1 base score of 8.8 reflects the vulnerability’s network attack vector (AV:N), low attack complexity (AC:L), requirement of low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits have been reported in the wild yet, the vulnerability’s characteristics make it highly exploitable. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for immediate attention by users of the affected software. Organizations relying on Ever Traduora for translation management or related services should consider this vulnerability critical and prioritize mitigation efforts.

The vulnerability allows attackers with limited privileges to forge JWT tokens and escalate their access rights, potentially gaining administrative or otherwise unauthorized control over the application. This can lead to unauthorized data access, modification, or deletion, severely compromising confidentiality, integrity, and availability of the system. For organizations, this could result in data breaches, service disruption, and loss of trust. Since JWTs are often used for session management and API authentication, the impact extends to any integrated systems relying on Ever Traduora’s authentication mechanisms. The ease of exploitation and high impact score make this a critical threat, especially in environments where sensitive or proprietary translation data is handled. The absence of known exploits in the wild does not reduce the urgency, as the vulnerability is straightforward to exploit once the hard-coded key is discovered or reverse-engineered.

1. Immediately replace the hard-coded JWT signing key with a securely generated, unique secret for each deployment. 2. Implement environment-based configuration for JWT keys rather than embedding them in source code. 3. Rotate existing JWT keys and invalidate all existing tokens to prevent misuse. 4. Apply the latest patches or updates from the vendor as soon as they become available. 5. Conduct a thorough audit of JWT usage and authentication flows to ensure no other hard-coded secrets exist. 6. Employ runtime application self-protection (RASP) or Web Application Firewalls (WAFs) to detect and block suspicious JWT token usage. 7. Educate development teams on secure credential management practices to prevent recurrence of hard-coded secrets. 8. Monitor logs for unusual authentication activity that may indicate exploitation attempts.
