CVE-2010-3573 in Java
Summary
by MITRE
Unspecified vulnerability in the Networking component in Oracle Java SE and Java for Business 6 Update 21 and 5.0 Update 25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the October 2010 CPU. Oracle has not commented on claims from a reliable downstream vendor that this is related to missing validation of request headers in the HttpURLConnection class when they are set by applets, which allows remote attackers to bypass the intended security policy.

The vulnerability identified as CVE-2010-3573 represents a critical security flaw within Oracle Java SE and Java for Business versions 6 Update 21 and 5.0 Update 25. This unspecified vulnerability resides within the Networking component of the Java platform and presents significant risks to system security through its potential to compromise confidentiality, integrity, and availability of affected systems. The vulnerability was initially documented in the October 2010 CPU update, highlighting the severity of the issue and its potential impact on enterprise environments that rely on Oracle Java implementations. The security implications extend beyond simple network connectivity issues, as this flaw operates at a fundamental level of Java's security architecture.
Technical analysis reveals that the vulnerability stems from insufficient validation of request headers within the HttpURLConnection class when these headers are manipulated by applets. This missing validation creates a pathway for malicious actors to bypass the intended security policies that govern Java applet behavior and network access restrictions. The flaw specifically targets the security boundaries that separate trusted applet environments from potentially malicious network requests, allowing attackers to manipulate header values that should normally be restricted or validated. This represents a classic case of inadequate input validation and security boundary enforcement, which aligns with CWE-20 (Improper Input Validation) and CWE-284 (Improper Access Control) categories within the CWE database. The vulnerability essentially allows attackers to circumvent the security model that Java implements to prevent applets from making unauthorized network connections or accessing restricted resources.
The operational impact of CVE-2010-3573 extends far beyond simple data corruption or service disruption, as it fundamentally undermines the security model that Java applets rely upon for safe execution in web environments. Attackers can exploit this vulnerability to perform unauthorized network operations, potentially accessing internal network resources that should remain protected from external access. The confidentiality aspect is particularly concerning as attackers may be able to intercept or modify network traffic that should remain protected, while integrity is compromised through potential data manipulation during network transactions. Availability can also be affected through denial of service attacks that leverage the vulnerability to exhaust system resources or disrupt normal network operations. This vulnerability directly relates to the ATT&CK technique T1059.007 (Command and Scripting Interpreter: Visual Basic) and T1071.004 (Application Layer Protocol: DNS) through the exploitation of Java applet security mechanisms and network protocol manipulation.
Mitigation strategies for CVE-2010-3573 should prioritize immediate patching of affected Java installations to the latest available versions that contain the necessary security fixes. Organizations must ensure that all systems running affected Java versions are updated promptly, as the vulnerability can be exploited remotely without user interaction. Network segmentation and firewall rules should be implemented to limit access to Java-enabled systems, particularly those running applet-based applications. Security administrators should also consider disabling Java applets in web browsers where possible, as this removes the attack surface entirely. Additionally, monitoring network traffic for suspicious header manipulation patterns and implementing proper access controls can help detect and prevent exploitation attempts. The vulnerability demonstrates the critical importance of maintaining up-to-date security patches and the dangers of relying on outdated software versions that may contain known security flaws. Organizations should implement comprehensive vulnerability management processes that include regular security assessments and continuous monitoring for similar issues within their Java-based environments.
