NOTE: this issue was SPLIT from CVE-2015-1848 per ADT2 due to different vulnerability types.

El demonio pcs (pcsd) en PCS 0.9.137 y anteriores no incluye el indicador HTTPOnly en una cabecera Set-Cookie, lo que facilita a atacantes remotos obtener información potencialmente sensible a través de acceso de secuencias de comandos a esta cookie. NOTA: este problema fue separado (SPLIT) de la CVE-2015-1848 por ADT2 debido a diferentes tipos de vulnerabilidad.

It was found that the pcs daemon did not sign cookies containing session data that were sent to clients connecting via the pcsd web UI. A remote attacker could use this flaw to forge cookies and bypass authorization checks, possibly gaining elevated privileges in the pcsd web UI.
