CVE-2024-22262: UriComponentsBuilder SSRF Vulnerability

CVE-2024-22262 Overview

Applications that use UriComponentsBuilder to parse an externally provided URL (e.g., through a query parameter) and perform validation checks on the host of the parsed URL may be vulnerable to an open redirect or SSRF attack if the URL is used after passing validation checks.

Critical Impact

This vulnerability allows malicious actors to redirect users to unintended sites or perform SSRF attacks, potentially exposing sensitive data.

Technical Details for CVE-2024-22262

Vulnerability Analysis

The vulnerability arises when applications improperly validate the host component of URLs parsed using UriComponentsBuilder, allowing attackers to craft URLs that bypass host validation logic.

Root Cause

The root cause is the incomplete validation of the host component within the URL, which leads to exploitation of the logic flaw.

Attack Vector

The attack can be launched remotely over a network, leveraging specially crafted URLs to achieve open redirect or SSRF conditions.

// Example exploitation code (sanitized)
String manipulatedUrl = "http://[email protected]";
UriComponentsBuilder.fromUriString(manipulatedUrl)
                    .build()
                    .toUri();

Detection Methods for CVE-2024-22262

Indicators of Compromise

• Unusual outbound traffic patterns
• Access logs showing requests to unexpected external sites
• Tampered URL parameters

Detection Strategies

Implement continuous monitoring of application logs and employ anomaly detection to identify unusual URL requests that might indicate SSRF.

Monitoring Recommendations

Regularly audit and review server access logs, focusing on URL parameters that contain suspicious hostnames or query strings.

How to Mitigate CVE-2024-22262

Immediate Actions Required

• Patch affected applications using the latest security updates.
• Audit application URL validation logic to block malformed URLs.
• Enable strict input validation and sanitization for all external inputs.

Patch Information

Refer to vendor-specific advisories for patch details. Ensure applications are updated to incorporate fixes against the vulnerability.

Workarounds

Implement additional validation measures to check URL components separately before further processing.

# Configuration example
DOMAIN_WHITELIST=("example.com" "trusted.com")

for domain in "${DOMAIN_WHITELIST[@]}"; do
    if [[ "${input_host}" == *"$domain"* ]]; then
        allow_connection=true
    fi
done
