Zenoss Core through 5 Beta 3 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka ZEN-15414, a similar issue to CVE-2003-1564.

Multiple cross-site request forgery (CSRF) vulnerabilities in Zenoss Core through 5 Beta 3 allow remote attackers to hijack the authentication of arbitrary users, aka ZEN-12653.

Zenoss Core through 5 Beta 3 allows remote attackers to obtain sensitive information by attempting a product-rename action with an invalid new name and then reading a stack trace, as demonstrated by internal URL information, aka ZEN-15382.

An unspecified endpoint in Zenoss Core through 5 Beta 3 allows remote attackers to cause a denial of service (CPU consumption) by triggering an arbitrary regular-expression match attempt, aka ZEN-15411.

Open redirect vulnerability in the login form in Zenoss Core before 4.2.5 SP161 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via the came_from parameter, aka ZEN-11998.

Zenoss Core through 5 Beta 3 does not require complex passwords, which makes it easier for remote attackers to obtain access via a brute-force attack, aka ZEN-15406.

Zenoss Core through 5 Beta 3 allows remote attackers to bypass intended access restrictions and place files in a directory with public (1) read or (2) execute access via a move action, aka ZEN-15386.

Zenoss Core through 5 Beta 3 uses a weak algorithm to hash passwords, which makes it easier for context-dependent attackers to obtain cleartext values via a brute-force attack on hash values in the database, aka ZEN-15413.

The default configuration of Zenoss Core before 5 allows remote attackers to read or modify database information by connecting to unspecified open ports, aka ZEN-15408.

Zenoss Core through 5 Beta 3 does not properly implement the Check For Updates feature, which allows remote attackers to execute arbitrary code by (1) spoofing the callhome server or (2) deploying a crafted web site that is visited during a login session, aka ZEN-12657.
