CVE-2025-54321

In Ascertia SigningHub through 8.6.8, there is a lack of rate limiting on the reset password function, leading to an email bombing vulnerability. An authenticated attacker can exploit this by automating reset password requests.

CVE-2025-54321 identifies a critical security vulnerability in Ascertia SigningHub, a widely used digital signature and document workflow platform, up to version 8.6.8. The vulnerability stems from the absence of rate limiting controls on the password reset functionality. This design flaw allows an unauthenticated attacker to repeatedly trigger password reset requests for a given user account without restriction. The consequence is an email bombing attack, where the targeted user's inbox is flooded with reset emails, potentially leading to denial-of-service conditions for the user and email infrastructure. The CVSS 3.1 base score of 9.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with an attack vector that is network-based, requires no privileges or user interaction, and affects all users of the service. The underlying CWE-799 classification highlights the failure to implement proper resource management controls, specifically rate limiting. While no public exploits have been reported yet, the ease of exploitation and critical impact make this a significant threat. Organizations relying on SigningHub for secure document signing and workflow automation must consider the risk of operational disruption and potential reputational harm if attackers leverage this vulnerability to disrupt user access or overwhelm email systems.
