CVE-2019-9511 (GCVE-0-2019-9511)

Vulnerability from cvelistv5 – Published: 2019-08-13 20:50 – Updated: 2024-08-04 21:54

Title

Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service

Summary

Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

Severity

7.5 (High)

CVE-2019-9513 (GCVE-0-2019-9513)

Vulnerability from cvelistv5 – Published: 2019-08-13 20:50 – Updated: 2024-08-04 21:54

Title

Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service

Summary

Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.

Severity

7.5 (High)

CVE-2019-9516 (GCVE-0-2019-9516)

Vulnerability from cvelistv5 – Published: 2019-08-13 20:50 – Updated: 2024-08-04 21:54

Title

Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service

Summary

Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.

Severity

7.5 (High)

The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory."

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.
