CVE-2025-67505
📋 TL;DR
A race condition vulnerability in Okta Java Management SDK versions 11.0.0 through 20.0.0 allows concurrent API requests to interfere with each other, potentially causing response data from one request to appear in another request's response. This affects applications using the Okta Java SDK for API interactions. The vulnerability is fixed in version 20.0.1.
💻 Affected Systems
- Okta Java Management SDK
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Sensitive data leakage or unauthorized actions if response headers/status codes from privileged requests influence unprivileged requests, potentially leading to authentication bypass or data exposure.
Likely Case
Intermittent API errors, incorrect status codes, or mixed response data causing application instability and potential data integrity issues.
If Mitigated
Application errors or degraded functionality without security compromise if proper input validation and error handling are implemented.
🎯 Exploit Status
Exploitation requires concurrent API requests and specific timing conditions. Requires access to the application using the vulnerable SDK.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 20.0.1
Vendor Advisory: https://github.com/okta/okta-sdk-java/security/advisories/GHSA-j5gq-897m-2rff
Restart Required: Yes
Instructions:
1. Update pom.xml or build.gradle to use okta-sdk-java version 20.0.1 or higher. 2. Rebuild and redeploy the application. 3. Restart the application server.
🔧 Temporary Workarounds
Implement request synchronization
allAdd synchronization blocks around ApiClient usage to prevent concurrent access
// Java code: synchronized(apiClient) { apiClient.callApi(...); }
Use thread-local ApiClient instances
allCreate separate ApiClient instances for each thread to avoid shared state
// Java code: ThreadLocal<ApiClient> apiClientThreadLocal = ThreadLocal.withInitial(ApiClient::new);
🧯 If You Can't Patch
- Implement rate limiting to reduce concurrent requests
- Add monitoring for unusual response patterns or status codes
🔍 How to Verify
Check if Vulnerable:
Check the SDK version in pom.xml, build.gradle, or by examining the deployed JAR file. Versions 11.0.0 through 20.0.0 are vulnerable.Check Version:
grep -i 'okta-sdk-java' pom.xml build.gradle || unzip -p *.jar META-INF/MANIFEST.MF | grep -i versionVerify Fix Applied:
Verify the SDK version is 20.0.1 or higher and test concurrent API requests for correct response isolation.📡 Detection & Monitoring
Log Indicators:
- Unexpected status codes in API responses
- Mixed response data between different requests
- Concurrent API request errors
Network Indicators:
- Unusual patterns in API response timing
- Inconsistent response headers for similar requests
SIEM Query:
source="application_logs" AND ("unexpected status" OR "concurrent error" OR "response mismatch")
