Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the RADIUS authentication module opens an unconnected datagram socket and trusts the first UDP datagram received on the client source port. The receive path does not verify the source IP and port, match the response identifier to the outstanding request, or verify the RFC 2865 Response Authenticator; the RFC 2869 Message-Authenticator is neither sent nor required. Any non-Reject/non-Challenge packet is treated as success. On a deployment with a RADIUS module instance enabled on a login chain, an unauthenticated network attacker can race the real server on-path or spray forged Access-Accept packets off-path and obtain a session for any RADIUS-mapped username without knowing the shared secret. Unlike CVE-2024-3596, exploitation requires no MD5 chosen-prefix forgery because no response authenticator is checked. The resulting session carries the impersonated principal's privileges. This issue is fixed in version 16.1.1.

A vulnerability database tells you what is broken. Attack surface management tells you where it is running: it discovers your internet-facing assets and flags the ones affected by issues like this one.
What is attack surface management? →A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.
CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.
A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.
Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.
Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.
SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
