Summary - Open redirect when resetting connections. When cpsrvd determines that it is necessary to reset a HTTP connection, it sends a 307 or 308 redirect response to the client. The Location header specified in this response was not escaped correctly and could be used by an attacker as an open redirect. This issue was discovered by Ian Dunn of WordPress.

Summary - Stored XSS in WHM MultiPHP Manager interface. The errors generated by the WHM MultiPHP Manager interface did not apply context-appropriate escaping. Because of this, it was possible for an attacker to generate an error message containing arbitrary code in the rendered page. This issue was discovered by the cPanel Security Team.

SEC-465
Summary - Arbitrary code execution as root via dnssec adminbin. The dnssec adminbin did not adequately validate the nsec_config or algo_config parameters. By injecting malicious data into these parameters, it was possible for attacker to execute arbitrary code on the system. This issue was discovered by the cPanel Security Team.

Summary - WebDAV backup transport writes debug files containing sensitive information. The WebDAV backup transport module enabled debug logging in HTTP::DAV. This debug information was written to a hardcoded file in an unsafe location. This file contained sensitive information. This could allow an attacker access to the remote WebDAV server. This issue was discovered by the cPanel Security Team.
