DoS vulnerabilities persist in ESAPI file uploads despite remediation of CVE-2023-24998

ESAPI 2.5.2.0 and later addressed the DoS vulnerability described in CVE-2023-24998, which Apache Commons FileUpload 1.5 attempted to remediate. But while writing up a new security bulletin regarding the impact on the affected ESAPI HTTPUtilities.getFileUploads methods (or more specifically those methods in the DefaultHTTPUtilities implementation class), I realized that a DoS vulnerability still persists in ESAPI and for that matter in Apache Commons FileUpload as well.

Missing Cryptographic Step in OWASP Enterprise Security API for Java

The authenticated-encryption feature in the symmetric-encryption implementation in the OWASP Enterprise Security API (ESAPI) for Java 2.x before 2.1.0 does not properly resist tampering with serialized ciphertext, which makes it easier for remote attackers to bypass intended cryptographic protection mechanisms via an attack against authenticity in the default configuration, involving a null MAC and a zero MAC length.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

ESAPI (The OWASP Enterprise Security API) is a free, open source, web application security control library. Prior to version 2.3.0.0, there is a potential for a cross-site scripting vulnerability in ESAPI caused by a incorrect regular expression for onsiteURL in the antisamy-esapi.xml configuration file that can cause javascript: URLs to fail to be correctly sanitized. This issue is patched in ESAPI 2.3.0.0. As a workaround, manually edit the antisamy-esapi.xml configuration …

Path traversal in the OWASP Enterprise Security API

ESAPI (The OWASP Enterprise Security API) is a free, open source, web application security control library. Prior to version 2.3.0.0, the default implementation of Validator.getValidDirectoryPath(String, String, File, boolean) may incorrectly treat the tested input string as a child of the specified parent directory. This potentially could allow control-flow bypass checks to be defeated if an attack can specify the entire string representing the 'input' path. This vulnerability is patched in …

MAC Bypass in Symmetric Encryption

The authenticated-encryption feature in the symmetric-encryption implementation in the this package does not properly resist tampering with serialized ciphertext, which makes it easier for remote attackers to bypass intended cryptographic protection mechanisms via an attack against the intended cipher mode in a non-default configuration, a different vulnerability than CVE-2013-5679.
