Описание
NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_dav_module module that might allow an attacker to trigger a buffer overflow to the NGINX worker process; this vulnerability may result in termination of the NGINX worker process or modification of source or destination file names outside the document root. This issue affects NGINX Open Source and NGINX Plus when the configuration file uses DAV module MOVE or COPY methods, prefix location (nonregular expression location configuration), and alias directives. The integrity impact is constrained because the NGINX worker process user has low privileges and does not have access to the entire system. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A flaw was found in NGINX. A remote attacker can exploit a buffer overflow vulnerability within the ngx_http_dav_module module. This occurs when the NGINX configuration uses DAV module MOVE or COPY methods in conjunction with prefix location and alias directives. Successful exploitation may lead to the termination of the NGINX worker process, resulting in a Denial of Service (DoS), or allow for the modification of source or destination file names outside the intended document root.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
