Vulnerability from variot - Updated: 2025-12-22 21:50An integer overflow exists in HAProxy 2.0 through 2.5 in htx_add_header 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. HAProxy Exists in an integer overflow vulnerability.Information may be tampered with. HAProxy is an open source TCP/HTTP load balancing server from the French HAProxy= company. =
There is an input validation error vulnerability in HAProxy, which stems from the lack of header name length checking in the htx_add_header() and htx_add_trailer() functions in HAProxy, which can be exploited by attackers to cause request smuggling attacks or response splitting attacks.

Package : haproxy CVE ID : CVE-2021-40346
Ori Hollander reported that missing header name length checks in the htx_add_header() and htx_add_trailer() functions in HAProxy, a fast and reliable load balancing reverse proxy, could result in request smuggling attacks or response splitting attacks.
Additionally this update addresses #993303 introduced in DSA 4960-1 causing HAProxy to fail serving URLs with HTTP/2 containing '//'.
For the stable distribution (bullseye), this problem has been fixed in version 2.2.9-2+deb11u2.
We recommend that you upgrade your haproxy packages.
For the detailed security status of haproxy please refer to its security tracker page at: https://security-tracker.debian.org/tracker/haproxy

HAProxy Exists in an integer overflow vulnerability.Information may be tampered with. HAProxy is an open source TCP/HTTP load balancing server from the French HAProxy= company. =\n\r\n\r\nThere is an input validation error vulnerability in HAProxy, which stems from the lack of header name length checking in the htx_add_header() and htx_add_trailer() functions in HAProxy, which can be exploited by attackers to cause request smuggling attacks or response splitting attacks.

CVE-2023-25725 (GCVE-0-2023-25725)
Vulnerability from nvd – Published: 2023-02-14 00:00 – Updated: 2025-03-20 19:14
VLAI?
Summary
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.

VLAI?
Summary
An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It does not ensure that the scheme and path portions of a URI have the expected characters. For example, the authority field (as observed on a target HTTP/2 server) might differ from what the routing rules were intended to achieve.
Severity ?
No CVSS data available.

CVE-2023-25725 (GCVE-0-2023-25725)
Vulnerability from cvelistv5 – Published: 2023-02-14 00:00 – Updated: 2025-03-20 19:14
VLAI?
Summary
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.
