Apm Server
Monthly
Persistent denial of service in Elastic APM Server allows an authenticated user with write access to source map content to upload specially crafted, highly compressed payloads that exhaust server memory upon processing. The condition (CWE-409, CAPEC-130) is self-reinforcing: every restart triggers re-processing of the stored content and re-crashes the server, making recovery impossible without manual removal of the malicious content. No public exploit code has been identified and the vulnerability is not listed in CISA KEV; however, the persistence characteristic significantly elevates operational impact compared to a transient DoS.
APM server logs contain document body from a partially failed bulk index request. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
An issue was discovered whereby APM Server could log at ERROR level, a response from Elasticsearch indicating that indexing the document failed and that response would contain parts of the original. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
It was discovered that when acting as TLS clients, Beats, Elastic Agent, APM Server, and Fleet Server did not verify whether the server certificate is valid for the target IP address; however,. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
