- Fix
1.11.13- Upgrade zendframework/zendframework1 to this version or later
Description
(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.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| zendframework/zendframework1 | >= 1.0, < 1.11.13 |
1.11.13 |
| zendframework/zendframework1 | >= 1.12.0-rc1, < 1.12.0 |
1.12.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
zendframework/zendframework1 Packagist → 1.11.13
- composer
composer require zendframework/zendframework1:^1.11.13
Weakness
CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')
The product uses XML documents and allows their structure to be defined with a Document Type Definition (DTD), but it does not properly control the number of recursive definitions of entities.
How to prevent it
- Operation: If possible, prohibit the use of DTDs or use an XML parser that limits the expansion of recursive DTD entities.
- Implementation: Before parsing XML files with associated DTDs, scan for recursive entity declarations and do not continue parsing potentially explosive content.
