DescriptionCVE.org

Improper neutralization of special elements used in an LDAP query ('LDAP injection') vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA bcprov on all (prov modules). LDAP Injection Vulnerability in LDAPStoreHelper.java

This issue affects BC-JAVA: from 1.49 before 1.84.

AnalysisAI

LDAP injection in Bouncy Castle BC-JAVA bcprov module (versions 1.49 through 1.83) allows remote unauthenticated attackers to manipulate LDAP queries via specially crafted input to LDAPStoreHelper.java, enabling complete compromise of confidentiality, integrity, and availability across security boundaries. This critical vulnerability (CVSS 10.0) affects a widely deployed cryptographic library used throughout the Java ecosystem. No active exploitation confirmed (not in CISA KEV), but the attack r

Technical ContextAI

Bouncy Castle BC-JAVA is a foundational cryptographic library for Java providing implementations of cryptographic algorithms, X.509 certificate handling, and PKI utilities. The vulnerability resides in LDAPStoreHelper.java within the provider (bcprov) module, which handles LDAP-based certificate and CRL retrieval operations. CWE-90 (LDAP Injection) occurs when user-controllable data is concatenated into LDAP query strings without proper sanitization of special LDAP metacharacters (parentheses, asterisks, null bytes, backslashes). Attackers can inject LDAP filter operators to bypass authentication checks, extract sensitive directory data, or modify query logic. The bcprov module is embedded in countless Java applications, middleware, and enterprise systems that perform certificate validation or directory operations. Affected CPE: cpe:2.3:a:legion_of_the_bouncy_castle_inc.:bc-java spanning a 35-version range (1.49 to 1.83), representing years of production deployments.

RemediationAI

Upgrade BC-JAVA bcprov module to version 1.84 or later, which contains input validation fixes for LDAP query construction in LDAPStoreHelper.java. Organizations should inventory all Java applications and dependencies to identify embedded Bouncy Castle versions using dependency scanning tools (Maven dependency tree, Gradle dependencies, or SBOM analysis). For systems where immediate upgrade is not feasible, implement compensating controls by restricting network access to LDAP directory services, validating and sanitizing all external input before passing to certificate validation routines, and disabling LDAP-based certificate retrieval features if not operationally required. Review application logs for suspicious LDAP query patterns or unexpected directory access. Consult the official vendor security advisory at https://github.com/bcgit/bc-java/wiki/CVE%E2%80%902026%E2%80%900636 for additional mitigation guidance and technical details. Given the 35-version span of affected releases, prioritize patching based on whether applications actively use the LDAPStoreHelper functionality rather than just including the library.
