Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU71431
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-0056
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the http_wait_for_response() function when handling HTTP/2 requests. A remote attacker can send a specially crafted HTTP request the proxy server and perform a denial of service (DoS) attack.
MitigationUpdate the affected package haproxy to the latest version.

2) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU72334
Risk: Medium
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-25725
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP/1 requests. A remote attacker can send a specially crafted HTTP request with empty fields, 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
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
MitigationUpdate the affected package haproxy to the latest version.
