VAR-201708-0218

Vulnerability from variot - Updated: 2023-12-25 20:53

The HTTP/2 header parser in Apache Tomcat 9.0.0.M1 to 9.0.0.M11 and 8.5.0 to 8.5.6 entered an infinite loop if a header was received that was larger than the available buffer. This made a denial of service attack possible. The Apache Software Foundation From Apache Tomcat Updates for the following multiple vulnerabilities have been released: * * HTTP Response falsification (CVE-2016-6816) * * Service operation interruption (DoS) (CVE-2016-6817) * * Arbitrary code execution (CVE-2016-8735)Expected impact varies depending on each vulnerability, but information leakage, service operation interruption (DoS) May be affected by arbitrary code execution. Apache Tomcat is prone to a denial-of-service vulnerability. Attackers may leverage this issue to cause denial-of-service conditions. The following versions are affected: Apache Tomcat 9.0.0.M1 through 9.0.0.M11 Apache Tomcat 8.5.0 through 8.5.6

The Apache Software Foundation From Apache Tomcat Updates for the following multiple vulnerabilities have been released: * * HTTP Response falsification (CVE-2016-6816) * * Service operation interruption (DoS) (CVE-2016-6817) * * Arbitrary code execution (CVE-2016-8735)Expected impact varies depending on each vulnerability, but information leakage, service operation interruption (DoS) May be affected by arbitrary code execution. Apache Tomcat is prone to a denial-of-service vulnerability. \nAttackers may leverage this issue to cause denial-of-service conditions. \nThe following versions are affected:\nApache Tomcat 9.0.0.M1 through 9.0.0.M11\nApache Tomcat 8.5.0 through 8.5.6",

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
