CWE-1035

Grouping Prohibited

OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities

Status: Incomplete

API response cwe.mitre.org

Weaknesses in this category are related to the A9 category in the OWASP Top Ten 2017.

Grouping entries organize the catalogue and should not be used to map the root cause of a vulnerability.

Mapping guidance

This entry is a Grouping. Using groupings for mapping has been discouraged since 2019. They are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves.

See member weaknesses of this category.

Notes

Relationship

This is an unusual category. CWE does not cover the limitations of human processes and procedures that cannot be described in terms of a specific technical weakness as resident in the code, architecture, or configuration of the software. Since "known vulnerabilities" can arise from any kind of weakness, it is not possible to map this OWASP category to other CWE entries, since it would effectively require mapping this category to ALL weaknesses.

CVE-2026-93558 (GCVE-0-2026-93558)

Vulnerability from cvelistv5 – Published: 2026-09-18 14:09 – Updated: 2026-11-06 17:12

Title
Io.netty/netty-codec-http: netty: unbounded per-connection queue growth in websocketserverextensionhandler leads to denial of service
Summary
A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive memory. Eventually, this can cause the Java Virtual Machine (JVM) to exhaust its heap, resulting in a Denial of Service (DoS) for the affected server.

CVE-2026-93494 (GCVE-0-2026-93494)

Vulnerability from cvelistv5 – Published: 2026-09-18 07:39 – Updated: 2026-09-25 08:02

Title
Io.netty/netty-codec-stomp: netty: bytebuf leak in stompsubframedecoder when a frame body is never terminated
Summary
A flaw was found in Netty's StompSubframeDecoder component. A remote attacker can exploit this vulnerability by sending a specially crafted STOMP frame body without its terminating null byte. This causes the decoder to allocate a ByteBuf (a buffer for bytes) that is never released, leading to a permanent memory leak. Over time, this uncontrolled memory consumption can result in a Denial of Service (DoS) for the application using the affected STOMP codec.

CVE-2026-93492 (GCVE-0-2026-93492)

Vulnerability from cvelistv5 – Published: 2026-09-18 12:49 – Updated: 2026-11-06 17:32

Title
Io.netty/netty-codec-http2: netty: http/2 hpackencoder dos with large table size
Summary
A flaw was found in Netty's HTTP/2 HpackEncoder. A remote attacker can exploit this by sending HTTP/2 SETTINGS frames with a very large MAX_HEADER_TABLE_SIZE. This causes the HpackEncoder to store an excessive number of unique headers, leading to increased CPU usage and memory consumption, ultimately resulting in a Denial of Service (DoS).
