CVE-2023-31442
7.5 · HIGHOverview
CVE-2023-31442 is a high-severity vulnerability affecting lightbend akka_actor. It was published on May 11, 2023 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
In Lightbend Akka before 2.8.1, the async-dns resolver (used by Discovery in DNS mode and transitively by Cluster Bootstrap) uses predictable DNS transaction IDs when resolving DNS records, making DNS resolution subject to poisoning by an attacker. If the application performing discovery does not validate (e.g., via TLS) the authenticity of the discovered service, this may result in exfiltration of application data (e.g., persistence events may be published to an unintended Kafka broker). If such validation is performed, then the poisoning constitutes a denial of access to the intended service. This affects Akka 2.5.14 through 2.8.0, and Akka Discovery through 2.8.0.
Remediation
Check the references section for vendor advisories and patches from lightbend. Update akka_actor to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
