K000132703: HAProxy vulnerability CVE-2021-40346

Security Advisory Description An integer overflow exists in HAProxy 2.0 through 2.5 in htxaddheader that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs. CVE-2021-40346 Impact There is no...

haproxy: segfault DoS

An uncontrolled resource consumption vulnerability was discovered in HAProxy which could crash the service. This issue could allow an authenticated remote attacker to run a specially crafted malicious server in an OpenShift cluster. The biggest impact is to availability...

codec-haproxy: HAProxyMessageDecoder Stack Exhaustion DoS

A flaw was found in codec-haproxy from the Netty project. This flaw allows an attacker to build a malformed crafted message and cause infinite recursion, causing stack exhaustion and leading to a denial of service DoS...

HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations aka "request smuggling." The HTTP header parsers in HAProxy may accept empty header field names which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1. For HTTP/2 and HTTP/3 the impact is limited because the headers disappear before being parsed and processed as if they had not been sent by the client. The fixed versions are 2.7.3 2.6.9 2.5.12 2.4.22 2.2.29 and 2.0.31.

Vulnerability fixed in HAProxy

HAProxy has fixed a vulnerability in all supported versions of HAProxy. Because headers are not always correctly processed, other headers can potentially become hidden from the parser of the proxy. This can cause a so-called "Request Smuggling occur. Request Smuggling attacks can lead to...

SUSE CVE-2018-10184

An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the maxframesize setting instead of being checked against the bufsize. The maxframesize only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the...
