AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability involves the use of hard-coded credentials in Avantra software versions before 25.3.0. Hard-coded credentials are fixed usernames or passwords embedded directly in the software code, which can be discovered and exploited by attackers.
Because of these hard-coded credentials, unauthorized users can access functionality that is not properly restricted by Access Control Lists (ACLs), potentially bypassing normal security controls.
How can this vulnerability impact me? :
Exploitation of this vulnerability can allow attackers to gain unauthorized access to certain functions within the Avantra software without needing proper permissions.
This unauthorized access can lead to information disclosure and integrity issues, as indicated by the CVSS impact metrics (Confidentiality: Low, Integrity: Low). However, availability is not affected.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
