Open redirect vulnerability in zport/aclusers/cookieAuthHelper/loginform in Zenoss 4.2.5 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the camefrom parameter.

Cross-site scripting (XSS) vulnerability in Zenoss 4.2.5 allows remote attackers to inject arbitrary web script or HTML via the title of a device.

Multiple cross-site request forgery (CSRF) vulnerabilities in Zenoss 2.3.3, and other versions before 2.5, allow remote attackers to hijack the authentication of an administrator for (1) requests that reset user passwords via zport/dmd/ZenUsers/admin, and (2) requests that change user commands, which allows for remote execution of system commands via zport/dmd/userCommands/.

Multiple SQL injection vulnerabilities in zport/dmd/Events/getJSONEventsInfo in Zenoss 2.3.3, and other versions before 2.5, allow remote authenticated users to execute arbitrary SQL commands via the (1) severity, (2) state, (3) filter, (4) offset, and (5) count parameters.

Zenoss Core 3.x contains a command injection vulnerability in the showDaemonXMLConfig endpoint. The daemon parameter is passed directly to a Popen() call in ZenossInfo.py without proper sanitation, allowing authenticated users to execute arbitrary commands on the server as the zenoss user.

Zenoss Core before 4.2.5 SP161 sets an infinite lifetime for the session ID cookie, which makes it easier for remote attackers to hijack sessions by leveraging an unattended workstation, aka ZEN-12691.

Zenoss Core through 5 Beta 3 allows remote authenticated users to obtain sensitive (1) user account, (2) e-mail address, and (3) role information by visiting the ZenUsers (aka User Manager) page, aka ZEN-15389.

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 stores cleartext passwords in the session database, which might allow local users to obtain sensitive information by reading database entries, aka ZEN-15416.

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 does not include the HTTPOnly flag in a Set-Cookie header for the authentication cookie, which makes it easier for remote attackers to obtain credential information via script access to this cookie, aka ZEN-10418.

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.

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 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.

Multiple format string vulnerabilities in the python module in RRDtool, as used in Zenoss Core before 4.2.5 and other products, allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted third argument to the rrdtool.graph function, aka ZEN-15415, a related issue to CVE-2013-2131.

Multiple cross-site scripting (XSS) vulnerabilities in Zenoss Core through 5 Beta 3 allow remote attackers to inject arbitrary web script or HTML via an attribute in a (1) device name, (2) device detail, (3) report name, (4) report detail, or (5) portlet name, or (6) a string to a helper method, aka ZEN-15381 and ZEN-15410.

Zenoss Core through 5 Beta 3 does not require a password for modifying the pager command string, which allows remote attackers to execute arbitrary commands or cause a denial of service (paging outage) by leveraging an unattended workstation, aka ZEN-15412.

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.

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.

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 camefrom parameter, aka ZEN-11998.

Zenoss Core through 5 Beta 3 allows remote attackers to bypass intended access restrictions by using a web-endpoint URL to invoke an object helper method, aka ZEN-15407.

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.

A vulnerability classified as problematic was found in Zenoss Dashboard up to 1.3.4. Affected by this vulnerability is an unknown functionality of the file ZenPacks/zenoss/Dashboard/browser/resources/js/defaultportlets.js. The manipulation of the argument HTMLString leads to cross site scripting. The attack can be launched remotely. Upgrading to version 1.3.5 is able to address this issue. The identifier of the patch is f462285a0a2d7e1a9255b0820240b94a43b00a44. It is recommended to upgrade the affected component. The identifier VDB-217153 was assigned to this vulnerability.

The XML-RPC subsystem in Zenoss 2.5.3 allows XXE attacks that lead to unauthenticated information disclosure via port 9988.

pyraw in Zenoss 2.5.3 allows local privilege escalation by modifying environment variables to redirect execution before privileges are dropped, aka ZEN-31765.

Thomas Pollet (thomas.pollet) reports:

Also, the rrdtool python module crashes on format string exploit $ python -c "import rrdtool rrdtool.graph('/tmp/out.png','-f','%n%n')" Segmentation fault

this module is used by zenoss to create graphs (zenoss users are able to pass arguments to rrdtool).
