The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Multiple unspecified vulnerabilities in WorldClient in Alt-N MDaemon before 10.02 have unknown impact and attack vectors, probably related to cross-site scripting (XSS) and WorldClient DLL 10.0.1, a different vulnerability than CVE-2008-6893.

Cross-site scripting (XSS) vulnerability in Alt-N MDaemon WorldClient 10.0.2, when Internet Explorer 7 is used, allows remote attackers to inject arbitrary web script or HTML via a crafted img tag.

Stack-based buffer overflow in SecurityGateway.dll in Alt-N Technologies SecurityGateway 1.0.1 allows remote attackers to execute arbitrary code via a long username parameter.

Unspecified vulnerability in DomainPOP in Alt-N Technologies MDaemon before 9.61 allows remote attackers to cause a denial of service (crash) via malformed messages.

MDaemon 9.0.5, 9.0.6, 9.51, and 9.53, and possibly other versions, installs the MDaemon application folder with insecure permissions (Users create files/directories), which allows local users to execute arbitrary code by creating malicious RASAPI32.DLL or MPRAPI.DLL libraries in the MDaemon\APP folder, which is an untrusted search path element due to insecure permissions.

Multiple unspecified vulnerabilities in MDaemon and WorldClient in Alt-N Technologies MDaemon before 9.50 allow attackers to cause a denial of service (memory consumption) via unspecified vectors resulting in memory leaks.

Unspecified vulnerability in WorldClient in Alt-N Technologies MDaemon before 9.50 has unknown impact and attack vectors related to a "JavaScript exploit."

The useredit_account.wdm module in Alt-N WebAdmin 3.2.5 running with MDaemon 9.0.6, and possibly earlier versions, allows remote authenticated domain administrators to gain privileges and obtain access to the system mail queue by modifying the mailbox of the MDaemon user account to use the mailbox of another account.

Multiple heap-based buffer overflows in the POP3 server in Alt-N Technologies MDaemon before 9.0.6 allow remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via long strings that contain '@' characters in the (1) USER and (2) APOP commands.
