An issue found in Zend Framework v.3.1.3 and before allow a remote attacker to execute arbitrary code via the unserialize function. Note: This has been disputed by third parties as incomplete and incorrect. The framework does not have a version that surpasses 2.x.x and was deprecated in early 2020.
ZendTo before 6.06-4 Beta allows XSS during the display of a drop-off in which a filename has unexpected characters.
Laminas Project laminas-http before 2.14.2, and Zend Framework 3.0.0, has a deserialization vulnerability that can lead to remote code execution if the content is controllable, related to the __destruct method of the Zend\Http\Response\Stream class in Stream.php. NOTE: Zend Framework is no longer supported by the maintainer. NOTE: the laminas-http vendor considers this a "vulnerability in the PHP language itself" but has added certain type checking as a way to prevent exploitation in (unrecommended) use cases where attacker-supplied data can be deserialized
lib/NSSDropbox.php in ZendTo prior to 5.22-2 Beta failed to properly check for equality when validating the session cookie, allowing an attacker to gain administrative access with a large number of requests.

This attack appear to be exploitable via HTTP POST request. This vulnerability appears to have been fixed in 5.16-1 Beta.
Zend Debugger in Zend Server before 9.1.3 has XSS, aka ZSR-2455.
The Zend_Db_Select::order function in Zend Framework before 1.12.7 does not properly handle parentheses, which allows remote attackers to conduct SQL injection attacks via unspecified vectors.

Cross-site request forgery (CSRF) vulnerability in Zend/Validator/Csrf in Zend Framework 2.3.x before 2.3.6 via null or malformed token identifiers.
The (1) order and (2) group methods in Zend_Db_Select in the Zend Framework before 1.12.19 might allow remote attackers to conduct SQL injection attacks via vectors related to use of the character pattern [\w]* in a regular expression.
The (1) order and (2) group methods in Zend_Db_Select in the Zend Framework before 1.12.20 might allow remote attackers to conduct SQL injection attacks by leveraging failure to remove comments from an SQL statement before validation.

Doctrine Annotations before 1.2.7, Cache before 1.3.2 and 1.4.x before 1.4.2, Common before 2.4.3 and 2.5.x before 2.5.1, ORM before 2.4.8 or 2.5.x before 2.5.1, MongoDB ODM before 1.0.2, and MongoDB ODM Bundle before 3.0.1 use world-writable permissions for cache directories, which allows local users to execute arbitrary PHP code with additional privileges by leveraging an application with the umask set to 0 and that executes cache entries as code.
The Zend_Xml_Security::scan in ZendXml before 1.0.1 and Zend Framework before 1.12.14, 2.x before 2.4.6, and 2.5.x before 2.5.2, when running under PHP-FPM in a threaded environment, allows remote attackers to bypass security checks and conduct XML external entity (XXE) and XML entity expansion (XEE) attacks via multibyte encoded characters.
The GenericConsumer class in the Consumer component in ZendOpenId before 2.0.2 and the Zend_OpenId_Consumer class in Zend Framework 1 before 1.12.4 does not verify that the openid_op_endpoint value identifies the same Identity Provider as the provider used in the association handle, which allows remote attackers to bypass authentication and spoof arbitrary OpenID identities by using a malicious OpenID Provider that generates OpenID tokens with arbitrary identifier and claimed_id values.
Zend Framework 1 (ZF1) before 1.12.4, Zend Framework 2 before 2.1.6 and 2.2.x before 2.2.6, ZendOpenId, ZendRest, ZendService_AudioScrobbler, ZendService_Nirvanix, ZendService_SlideShare, ZendService_Technorati, and ZendService_WindowsAzure before 2.0.2, ZendService_Amazon before 2.0.3, and ZendService_Api before 1.0.0 allow remote attackers to cause a denial of service (CPU consumption) via (1) recursive or (2) circular references in an XML entity definition in an XML DOCTYPE declaration, aka an XML Entity Expansion (XEE) attack.

NOTE: this issue exists because of an incomplete fix for CVE-2012-5657.
Zend Framework 1 (ZF1) before 1.12.4, Zend Framework 2 before 2.1.6 and 2.2.x before 2.2.6, ZendOpenId, ZendRest, ZendService_AudioScrobbler, ZendService_Nirvanix, ZendService_SlideShare, ZendService_Technorati, and ZendService_WindowsAzure before 2.0.2, ZendService_Amazon before 2.0.3, and ZendService_Api before 1.0.0 allow remote attackers to read arbitrary files, send HTTP requests to intranet servers, and possibly cause a denial of service (CPU and memory consumption) via an XML External Entity (XXE) attack. NOTE: this issue exists because of an incomplete fix for CVE-2012-5657.
The (1) Zend_Ldap class in Zend before 1.12.9 and (2) Zend\Ldap component in Zend 2.x before 2.2.8 and 2.3.x before 2.3.3 allows remote attackers to bypass authentication via a password starting with a null byte, which triggers an unauthenticated bind.
The GenericConsumer class in the Consumer component in ZendOpenId before 2.0.2 and the Zend_OpenId_Consumer class in Zend Framework 1 before 1.12.4 violate the OpenID 2.0 protocol by ensuring only that at least one field is signed, which allows remote attackers to bypass authentication by leveraging an assertion from an OpenID provider.

The (1) Zend_Feed_Rss and (2) Zend_Feed_Atom classes in Zend_Feed in Zend Framework 1.11.x before 1.11.15 and 1.12.x before 1.12.1 allow remote attackers to read arbitrary files, send HTTP requests to intranet servers, and possibly cause a denial of service (CPU and memory consumption) via an XML External Entity (XXE) attack.
(1) Zend_Dom, (2) Zend_Feed, (3) Zend_Soap, and (4) Zend_XmlRpc in Zend Framework 1.x before 1.11.13 and 1.12.x before 1.12.0 allow remote attackers to cause a denial of service (CPU consumption) via recursive or circular references in an XML entity definition in an XML DOCTYPE declaration, aka an XML Entity Expansion (XEE) attack.
(1) Zend_Dom, (2) Zend_Feed, and (3) Zend_Soap in Zend Framework 1.x before 1.11.13 and 1.12.x before 1.12.0 do not properly handle SimpleXMLElement classes, which allow remote attackers to read arbitrary files or create TCP connections via an external entity reference in a DOCTYPE element in an XML-RPC request, aka an XML external entity (XXE) injection attack, a different vulnerability than CVE-2012-3363.
Zend_XmlRpc in Zend Framework 1.x before 1.11.12 and 1.12.x before 1.12.0 does not properly handle SimpleXMLElement classes, which allows remote attackers to read arbitrary files or create TCP connections via an external entity reference in a DOCTYPE element in an XML-RPC request, aka an XML external entity (XXE) injection attack.
Untrusted search path vulnerability in the installation functionality in Zend Server 5.6.0 SP4, when installed in the top-level C:\ directory, might allow local users to gain privileges via a Trojan horse DLL in the C:\Zend\ZendServer\share\ZendFramework\bin directory, which may be added to the PATH system environment variable by an administrator, as demonstrated by a Trojan horse wlbsctrl.dll file used by the "IKE and AuthIP IPsec Keying Modules" system service in Windows Vista SP1, Windows Server 2008 SP2, Windows 7 SP1, and Windows 8 Release Preview. NOTE: CVE disputes this issue because the choice of C:\ (and the resulting unsafe PATH) is established by an administrative action that is not a default part of the Zend Server installation
Zend Framework 1.11.3 in Zend Server CE 5.1.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by Validate.php and certain other files.
The shutdown function in the Zend_Log_Writer_Mail class in Zend Framework (ZF) allows context-dependent attackers to send arbitrary e-mail messages to any recipient address via vectors related to "events not yet mailed."
Zend Platform 2.2.3 and earlier has incorrect ownership for scd.sh and certain other files, which allows local users to gain root privileges by modifying the files. NOTE: this only occurs when safe_mode and open_basedir are disabled; other settings require leverage for other vulnerabilities.

Multiple cross-site scripting (XSS) vulnerabilities in Zend Google Data Client Library (ZendGData) Preview 0.2.0 allow remote attackers to inject arbitrary web script or HTML via unspecified parameters in (1) basedemo.php and (2) calenderdemo.php in samples/, and other unspecified files.
