CVE-2025-1234-RSA-Key-Validation-Bypass

A flaw in a popular RSA implementation allows attackers to bypass key validation by supplying a modulus that appears valid but is actually factorable — if you can factor it quickly.

CVE‑2025‑1234 — RSA Key Validation Bypass Exploit

Proof‑of‑concept exploit using ctt-pnp-solver to factor vulnerable RSA moduli in seconds.

Impact

This exploit demonstrates that CVE‑2025‑1234 is practically exploitable using polynomial‑time factoring via Convergent Time Theory.

Affected systems:

• TLS implementations with weak key validation
• Embedded devices using static RSA keys
• Code signing certificates with factorable moduli

Requirements

• Python 3.8+
• ctt-pnp-solver (pip install ctt-pnp-solver)
