Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU4201
Risk: Critical
CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2012-1823
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to error when parsing QUERY_STRING parameters within PHP-CGI-based application (sapi/cgi/cgi_main.c). A remote attacker can send specially crafted HTTP request with query string without the "=" (equals sign) character, inject and execute arbitrary OS commands on vulnerable system with privileges of the web server.
Successful exploitation of the vulnerability results in denial of service or arbitrary code execution on the vulnerable system.
Note: the vulnerability was being actively exploited.
Update the affected packages.
PHP: 5.0 - 5.4.1

CVSSv3.1: 9.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2012-2311
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to error when parsing QUERY_STRING parameters within PHP-CGI-based application (sapi/cgi/cgi_main.c). A remote attacker can send specially crafted HTTP request with query string, contain a %3D sequence but no = (equals sign) character, inject and execute arbitrary OS commands on vulnerable system with privileges of the web server.
Successful exploitation of the vulnerability results in denial of service or arbitrary code execution on the vulnerable system.
This vulnerability is a result of an incomplete fix for SB2012050301.
Note: the vulnerability was being actively exploited.
Update the affected packages.
