Denial of service against HTTP/2 server implementations allows remote unauthenticated attackers to exhaust server resources by rapidly opening and immediately canceling (RST_STREAM) large numbers of streams over a single connection, a technique dubbed the 'Rapid Reset' attack. The flaw is confirmed actively exploited (CISA KEV) following large-scale weaponization observed August through October 2023, with publicly available exploit code and an EPSS score of 94.45% placing it in the 100th percentile for likelihood of exploitation. Virtually every major HTTP/2 stack - including nghttp2, Netty, Envoy, and Eclipse Jetty - is affected.
If you enable Basic Authentication in Pekko Management using the Java DSL, the authenticator may not be properly applied. Users that rely on authentication instead of making sure the Management API ports are only available to trusted users are recommended to upgrade to version 1.1.1, which fixes this issue. Akka was affected by the same issue and has released the fix in version 1.6.1.
Akka HTTP 10.1.x before 10.1.15 and 10.2.x before 10.2.7 can encounter stack exhaustion while parsing HTTP headers, which allows a remote attacker to conduct a Denial of Service attack by sending a. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Lightbend Akka 2.5.x before 2.5.16 allows message disclosure and modification because of an RNG error. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Akka HTTP versions <= 10.0.5 Illegal Media Range in Accept Header Causes StackOverflowError Leading to Denial of Service. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
Akka versions <=2.4.16 and 2.5-M1 are vulnerable to a java deserialization attack in its Remoting component resulting in remote code execution in the context of the ActorSystem. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. Epss exploitation probability 11.7%.
