CVE-2026-21010 is an improper input validation vulnerability in Samsung Retail Mode affecting Android 14, 15, and 16 prior to SMR Apr-2026 Release 1. The flaw allows a local attacker to supply crafted input that is not properly validated by the Retail Mode component, resulting in the ability to trigger privileged functions. Samsung indicates the issue was remediated by removing unnecessary implementation in the affected component.

This repository is a small Python proof-of-concept/demo for CVE-2026-21010, illustrating a SIP digest authentication replay flaw. It contains two code files: a vulnerable Flask-based simulator (sip_server_sim.py) and a replay client (exploit_sip_replay.py), plus a README and license. The server exposes POST /call on port 5060 and, when no Authorization header is present, returns a digest challenge with a fixed nonce (abc123). It does not track nonce reuse, so any subsequent request with the same captured Authorization header is accepted. The exploit script uses Python requests to POST to http://localhost:5060/call with a hardcoded captured digest Authorization header containing nonce abc123 and SIP URI sip:alice@example.com. Successful exploitation results in authentication bypass and a 'Call connected' response. The repository is not part of a larger exploit framework and is best classified as an operational PoC/demo of replay-based unauthorized call access rather than a full weaponized exploit.
