This security bulletin contains information about 2 vulnerabilities.

1) Authentication bypass

EUVDB-ID: #VU330

Risk: High

CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]

CVE-ID: CVE-2014-9222

CWE-ID: CWE-287 - Improper Authentication

2) Multiple buffer overflows

EUVDB-ID: #VU329

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2014-9223

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerabilities allow a remote attacker to execute arbitrary code on the target system.

The vulnerabilities exist due to a boundary error when handling user-supplied data. A remote attacker can send a specially crafted HTTP request to vulnerable web server, trigger buffer overflow and cause a denial of service condition or execute arbitrary code on the target system.

Successful exploitation of this vulnerability will result in compromise of the affected system.
