Apache IoTDB REST Authentication Accepts Stale Cached Credentials

Insufficient Session Expiration, Authentication Bypass by Capture-replay vulnerability in Apache IoTDB. REST Basic Authentication Accepts Stale Cached Credentials This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-28564 exposes a critical authentication bypass vulnerability in Apache IoTDB versions 1.0.0 through 2.0.9, where the REST API fails to properly expire sessions and accepts replayed cached credentials. This issue combines insufficient session expiration (CWE-294) with capture-replay vulnerabilities (CWE-613), allowing attackers to reuse intercepted authentication tokens to gain unauthorized access to IoTDB instances. With a CVSS score of 9.8, this affects any organization running vulnerable IoTDB versions, particularly those using REST APIs for time-series data management in industrial IoT, smart grid, and monitoring infrastructure deployments where data integrity and confidentiality are critical.

Casky.ai's 283 mapped security skills detect the attack patterns underlying this vulnerability by correlating MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Claude AI-powered analysis would identify suspicious indicators including: repeated authentication requests with identical session tokens across different timestamps, REST API calls bearing credentials outside their original network context, and sequential data access patterns following initial credential capture. The platform's extended reasoning capabilities correlate session management failures with replay attack signatures, helping teams distinguish legitimate authentication from captured-credential exploitation—enabling detection of attackers leveraging stale cached credentials to escalate privileges and access sensitive time-series data without legitimate session establishment.
