Multiple vulnerabilities in IBM Security Verify Access

1) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU22597

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-18277

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform HTTP request smuggling attack.

The vulnerability exists due to incorrect processing of messages with a missing transfer-encoding header, when HAProxy is configured in legacy mode. The server does not reject "chunked" value that combined with the "http-reuse always" setting can lead to HTTP request smuggling attack.

Risk: Low

CVSSv3.1: 2 [CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2455

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to incomplete fix for #VU40402 (CVE-2016-2193) that did not anticipate a scenario involving function inlining.
