🎯 CVE-Telco: All-Timeline Vulnerability Tracker

🏛️ Vulnerability Framework Mapping

All entries are mapped to the itu-t X.1500 (CYBEX) family and X.1031/X.1038 blueprints.

🕰️ The Security Timeline (1G to 6G+)

1️⃣ Era 1: The Trust Era (1G/2G)

• Historical Context: Security via obscurity; no encryption in 1G; weak 64-bit stream ciphers in 2G.
• Vulnerability Patterns:
  • COMP128-1 Flaw: SIM cloning via Ki recovery (Brute force in <8 hours).
  • A5/1 & A5/2 Crack: Real-time decryption of 2G air interface (CWE-327).
  • SS7 Intercept: Lack of authentication in signaling; SMS/Call hijacking (X.1031).
• Mission Impact: Complete loss of subscriber privacy and billing integrity.

2️⃣ Era 2: The Transition Era (3G/4G)

• Historical Context: Movement toward AKA (Authentication and Key Agreement) and Diameter/GTP.
• Vulnerability Patterns:
  • Kasumi/A5/3 Weakness: Related-key attacks on 3G encryption (CWE-327).
  • Diameter DoS: Signaling storm via malformed messages (X.1031).
  • GTP-U Breakout: Tunnel manipulation enabling IP spoofing and traffic redirection.
  • VoLTE/SIP Leak: Disclosure of user identity (IMSI) via IMS signaling headers.
• Mission Impact: Denial of Service (DoS) and core network compromise.

3️⃣ Era 3: The Cloud Era (5G)

• Context: Service Based Architecture (SBA), HTTP/2 APIs, and Network Slicing.
• High-Impact Patterns (2020-2025):
  • SBI API Abuse: Lack of authorization in the Service Based Interface (X.1038).
  • SUCI/SUPI Null-Cipher: Forcing the UE to transmit unencrypted identity.
  • AMF/UPF Buffer Overflow: Software-level vulnerabilities in core network functions (CVE-2023/2024 patterns).
  • Slice Isolation Failure: Cross-slice data leakage via misconfigured NFV/Kubernetes.
• Mission Impact: Lateral movement within the 5G Core (5GC) and slice takeover.

4️⃣ Era 4: The Intelligent Era (6G+)

• Future Context: AI-enabled RAN, Terahertz (THz) beams, and Quantum threats.
• Emerging Threats:
  • PQC Harvest-Now-Decrypt-Later: Quantum computers breaking legacy RSA/Elliptic Curve (PQC Mitigation: X.1031).
  • AI Model Poisoning: Adversarial attacks on RAN beamforming and optimization models.
  • THz Beam Squinting: Physical layer eavesdropping at extremely high frequencies.
• Mission Impact: Strategic decryption of historical data and AI-driven signal jamming.

🛠️ Operational Audit Priority

When conducting a field audit, prioritize the following based on the Full Chronology:

1. Legacy Fallback: Verify that the network cannot be downgraded to 2G/A5/1 or 3G/A5/3.
2. Signaling Hardening: Validate Diameter/GTP filters against known CVE-2023+ signatures.
3. SBA Authorization: Ensure all HTTP/2 NRF (Network Repository Function) queries require valid OAuth/SEPP tokens.

!IMPORTANTZero-Day Reporting: Any new vulnerability discovered during audit should be cross-referenced with itu-t X.1500 for reporting to the national CERT/CIRT as defined in Series-CYB.
