Description

This security bulletin contains information about 4 vulnerabilities.


1) Cross-site request forgery (CVE-ID: CVE-2012-4893)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.


2) Input validation error (CVE-ID: CVE-2012-2981)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote #AU# to read and manipulate data.

Webmin 1.590 and earlier allows remote authenticated users to execute arbitrary Perl code via a crafted file associated with the type (aka monitor type name) parameter.


3) Input validation error (CVE-ID: CVE-2012-2982)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:A/U:Clear


The vulnerability allows a remote #AU# to read and manipulate data.

file/show.cgi in Webmin 1.590 and earlier allows remote authenticated users to execute arbitrary commands via an invalid character in a pathname, as demonstrated by a | (pipe) character.


4) Improper Authentication (CVE-ID: CVE-2012-2983)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Green


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

file/edit_html.cgi in Webmin 1.590 and earlier does not perform an authorization check before showing a file's unedited contents, which allows remote attackers to read arbitrary files via the file field.
