Vulnerability Details:
Embedding Javascript code with certain parameters of oAuth API calls can lead to reflected script execution within the users context and a trusted domain.

Vulnerability type: CWE-36: Absolute Path Traversal
Vulnerable version: 7.4.1 and earlier
Vulnerable component: backend

CVE reference: CVE-2013-7140
CVSSv2: 7.4 (AV:N/AC:M/Au:S/C:C/I:N/A:N/E:P/RL:U/RC:C/CDP:MH/TD:H/CR:ND/IR:ND/AR:ND)

Vulnerability Details:
Using forged requests against the CalDAV interface can be used to reveal file contents stored at the server system. The SAX builder used to deserialize posted XML bodies at the WebDAV interface was used with the default values, thus potentially vulnerable against XML external entity attacks (XXE).

Risk:
Content of the requested file is returned to the attacker. This can be used to spy on credentials, configuration or other sensitive data stored at the server.

Solution:
Users should update to the latest available patch releases. The CalDAV interface should be disabled until a solution is provided.

CVSSv2: 5.7 (AV:N/AC:M/Au:N/C:P/I:N/A:N/E:POC/RL:U/RC:C/CDP:LM/TD:H/CR:ND/IR:ND/AR:ND)

Vulnerability Details:
Embedding Javascript code with the title of a mail filter rule leads to execution of the embedded code. This enables a stored cross-site scripting vulnerability that may be used in conjunction with other vulnerabilities or social engineering that placed malicious code at the vulnerable location.

Risk:
Malicious script code can be executed within a users context. This can lead to session hijacking or triggering unwanted actions like sending mail, deleting data etc.

Solution:
Users should update to the latest available patch releases. Users should not grant other users access to their account.
