CVE-2025-65831

7.5

Unknown · Unknown Application

The application utilizes the insecure MD5 hashing algorithm for password storage, potentially allowing attackers to crack hashes and gain unauthorized account access.

Executive summary

The use of the deprecated MD5 hashing algorithm in the affected application poses a significant risk of unauthorized account access due to the susceptibility of MD5 to collision and pre-image attacks.

Vulnerability

The application employs the cryptographically broken MD5 algorithm to protect user passwords, which can be bypassed by an unauthenticated attacker if the hash database is compromised or intercepted via network traffic.

Business impact

The exposure of hashed credentials through an insecure algorithm creates a high risk of credential harvesting and account takeover. With a CVSS score of 7.5, this vulnerability represents a significant threat to user privacy and organizational integrity, as it facilitates unauthorized access to sensitive accounts without requiring complex exploitation of the application logic itself.

Remediation

Immediate Action: Contact the software vendor to determine if a patch or configuration update exists to migrate password storage to a strong, salted hashing algorithm such as Argon2 or bcrypt.

Proactive Monitoring: Review authentication logs and database access patterns for signs of unauthorized data exfiltration or anomalous login activity.

Compensating Controls: Ensure all traffic to the application is encrypted via robust TLS configurations to prevent the interception of credentials during transit, and enforce multi-factor authentication (MFA) to mitigate the impact of potentially compromised passwords.

Exploitation status

Public Exploit Available: No

Analyst recommendation

Organizations should prioritize identifying whether their specific deployments of the affected software are using MD5 for password storage and coordinate with the vendor for a secure replacement. Given the high CVSS score, failure to address this cryptographic weakness leaves user credentials highly vulnerable to offline cracking attacks.
