OVERVIEW
A vulnerability has been identified in Parallels Plesk Panel
versions prior to 10.4.4 MU#58 and 11.0.9 MU#62. [1]
IMPACT
The vendor has provided the following information concerning the
vulnerability:
"Medium severity XML External Entity (XXE) issue affects PP versions
10.4.x and 11.0.x both Linux and Windows with installed Single
Sign-On (SSO) service. May be unexploitable depending on installed
libxml2 version. Impact is limited because SSO works under own
unprivileged user sso, it means only files available for this user
could be read.
Minor severity Cross-Site Scripting (XSS) issue affects PP versions
10.4.x and 11.0.x both Linux and Windows with installed Single
Sign-On (SSO) service." [1]
