Access Server
Monthly
HTTP request smuggling in OpenVPN Access Server 2.7.2 through 3.1.0 enables remote unauthenticated attackers to inject or manipulate backend requests when the Access Server is deployed behind a reverse proxy. The server incorrectly accepts bare line-feed (LF-only, without carriage return) characters inside HTTP header values, creating a parsing discrepancy between the front-end proxy and the Access Server backend - the hallmark of CWE-444. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog; however, the CVSS 4.0 score of 6.9 with integrity impact on both the vulnerable and subsequent systems indicates meaningful risk in typical enterprise VPN gateway deployments fronted by load balancers or reverse proxies.
Ericom Access Server 9.2.0 (for AccessNow and Ericom Blaze) allows SSRF to make outbound WebSocket connection requests on arbitrary TCP ports, and provides "Cannot connect to" error messages to. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
