TITLE

nginx of src/http/modules/ngx_http_dav_module.c Vulnerable to directory traversal

DESCRIPTION

Directory traversal vulnerability in src/http/modules/ngx_http_dav_module.c in nginx (aka Engine X) before 0.7.63, and 0.8.x before 0.8.17, allows remote authenticated users to create or overwrite arbitrary files via a .. (dot dot) in the Destination HTTP header for the WebDAV (1) COPY or (2) MOVE method. nginx of src/http/modules/ngx_http_dav_module.c Contains a directory traversal vulnerability.By a remotely authenticated user WebDAV (1) COPY Or (2) MOVE To the method .. The 'nginx' program is prone to multiple directory-traversal vulnerabilities because the software fails to sufficiently sanitize user-supplied input. An attacker can exploit these issues using directory-traversal strings ('../') to overwrite arbitrary files outside the root directory. These issues affect nginx 0.7.61 and 0.7.62; other versions may also be affected. ---------------------------------------------------------------------- Do you have VARM strategy implemented?

Successful exploitation requires that the server has been compiled with the http_dav_module and that the attacker is allowed to use the "MOVE" or "COPY" methods. The security issue is reported in version 0.7.61 and confirmed in version 0.7.62. SOLUTION: Restrict access to trusted users only.

Background ========== nginx is a robust, small, and high performance HTTP and reverse proxy server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/nginx < 1.0.14 >= 1.0.14 Description =========== Multiple vulnerabilities have been found in nginx: * The TLS protocol does not properly handle session renegotiation requests (CVE-2009-3555). * The "ngx_http_process_request_headers()" function in ngx_http_parse.c could cause a NULL pointer dereference (CVE-2009-3896). * The "ngx_resolver_copy()" function in ngx_resolver.c contains a boundary error which could cause a heap-based buffer overflow (CVE-2011-4315). * nginx does not properly parse HTTP header responses which could expose sensitive information (CVE-2012-1180). Impact ====== A remote attacker could possibly execute arbitrary code with the privileges of the nginx process, cause a Denial of Service condition, create or overwrite arbitrary files, or obtain sensitive information. Workaround ========== There is no known workaround at this time. Resolution ========== All nginx users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14" References ========== [ 1 ] CVE-2009-3555 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3555 [ 2 ] CVE-2009-3896 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3896 [ 3 ] CVE-2009-3898 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3898 [ 4 ] CVE-2011-4315 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4315 [ 5 ] CVE-2012-1180 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1180 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201203-22.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
