CVE-2022-46443

Bangresto is point-of-sale software some small restaurants and shops use to track orders and inventory. This flaw is like a staff member being able to sneak extra commands into the 'quantity' field of an order form and trick the system into showing or changing data they shouldn't be able to touch — including other customers' or sales records.

This matters to you if you run mesinkasir Bangresto 1.0 for point-of-sale, restaurant, or inventory management. Any user who already has a basic login account to the system can exploit this, so the risk grows with the number of staff or outside users who have accounts.

This should be treated as a priority to address soon, though it is not currently being actively exploited in the wild. Proof-of-concept detection tools exist and press attention has been sustained, which means awareness of the flaw is spreading even though no confirmed attacks or official fix exist yet. Act on access controls now while you wait for a vendor patch.

1. Identify all deployments of mesinkasir Bangresto 1.0 in your environment. 2. Confirm the vulnerable endpoint handles the 'itemqty[]' parameter without proper input sanitization/parameterized queries (CWE-89). 3. No official patch is currently available from the vendor — monitor the vendor's repository/release channel for a fixed version and apply it as soon as released. 4. As a temporary mitigation: enforce least-privilege on all application accounts, add input validation/WAF rules blocking SQL metacharacters in the itemqty[] parameter, and restrict database account permissions used by the app to minimize blast radius. 5. Review database logs and application logs for anomalous queries or unexpected data modifications tied to order quantity fields. 6. There is no CISA KEV listing and no confirmed in-the-wild exploitation, so this is not an emergency drop-everything patch, but should be remediated within normal vulnerability management SLAs given the high CVSS score (8.8) and low authentication bar (PR:L).

CVSS 3.1 score 8.8 (High), vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H — network-exploitable, low complexity, requires low-privilege authentication, no user interaction, with high impact to confidentiality, integrity, and availability. Weakness class is CWE-89 (SQL Injection) via the 'itemqty[]' parameter, allowing full read/write access to backend data. Not listed in CISA KEV; no confirmed in-the-wild exploitation. A detection template exists publicly (exploit maturity: PoC/detection-level, not weaponized exploit code confirmed in use). EPSS predicts a declining likelihood of exploitation activity. No vendor patch is currently available; press coverage has been sustained, indicating public awareness but not active attack campaigns.
