| CVE-2020-11100 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2024-08-04 | 8.8 High |
| In hpack_dht_insert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution. | ||||
| CVE-2021-40346 | 4 Debian, Fedoraproject, Haproxy and 1 more | 4 Debian Linux, Fedora, Haproxy and 1 more | 2024-08-04 | 7.5 High |
| An 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. | ||||
| CVE-2021-39241 | 4 Debian, Fedoraproject, Haproxy and 1 more | 4 Debian Linux, Fedora, Haproxy and 1 more | 2024-08-04 | 5.3 Medium |
| An issue was discovered in HAProxy 2.0 before 2.0.24, 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. An HTTP method name may contain a space followed by the name of a protected resource. It is possible that a server would interpret this as a request for that protected resource, such as in the "GET /admin? HTTP/1.1 /static/images HTTP/1.1" example. | ||||
| CVE-2021-39240 | 4 Debian, Fedoraproject, Haproxy and 1 more | 4 Debian Linux, Fedora, Haproxy and 1 more | 2024-08-04 | 7.5 High |
| 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. | ||||
| CVE-2021-39242 | 4 Debian, Fedoraproject, Haproxy and 1 more | 4 Debian Linux, Fedora, Haproxy and 1 more | 2024-08-04 | 7.5 High |
| 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 can lead to a situation with an attacker-controlled HTTP Host header, because a mismatch between Host and authority is mishandled. | ||||
| CVE-2022-0711 | 3 Debian, Haproxy, Redhat | 6 Debian Linux, Haproxy, Enterprise Linux and 3 more | 2024-08-02 | 7.5 High |
| A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability. | ||||
| CVE-2023-25950 | 1 Haproxy | 1 Haproxy | 2024-08-02 | 7.3 High |
| HTTP request/response smuggling vulnerability in HAProxy version 2.7.0, and 2.6.1 to 2.6.7 allows a remote attacker to alter a legitimate user's request. As a result, the attacker may obtain sensitive information or cause a denial-of-service (DoS) condition. | ||||
| CVE-2023-25725 | 3 Debian, Haproxy, Redhat | 6 Debian Linux, Haproxy, Ceph Storage and 3 more | 2024-08-02 | 9.1 Critical |
| 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. | ||||
| CVE-2023-0836 | 2 Haproxy, Redhat | 2 Haproxy, Enterprise Linux | 2024-08-02 | 7.5 High |
| An information leak vulnerability was discovered in HAProxy 2.1, 2.2 before 2.2.27, 2.3, 2.4 before 2.4.21, 2.5 before 2.5.11, 2.6 before 2.6.8, 2.7 before 2.7.1. There are 5 bytes left uninitialized in the connection buffer when encoding the FCGI_BEGIN_REQUEST record. Sensitive data may be disclosed to configured FastCGI backends in an unexpected way. | ||||
| CVE-2023-0056 | 3 Fedoraproject, Haproxy, Redhat | 12 Extra Packages For Enterprise Linux, Fedora, Haproxy and 9 more | 2024-08-02 | 6.5 Medium |
| 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. | ||||
