Missing authentication for critical function vulnerability in AKIN Software Computer Import Export Industry and Trade Ltd. CafePlus allows Accessing Functionality Not Properly Constrained by ACLs.
This issue affects CafePlus: from 12.05.03 before 12.05.04.
AnalysisAI
Missing authentication in AKIN Software's CafePlus versions 12.05.03 through 12.05.04 allows adjacent-network attackers to access privileged functionality without credentials. The flaw enables full compromise of confidentiality, integrity, and availability over an adjacent network vector, with no public exploit identified at time of analysis. Reported by Turkey's national CERT (TR-CERT), the issue stems from critical functions lacking proper ACL enforcement.
Technical ContextAI
CafePlus is a point-of-sale and management platform produced by AKIN Software Computer Import Export Industry and Trade Ltd., commonly deployed in Turkish cafe and hospitality environments. The root cause is CWE-306 (Missing Authentication for Critical Function), meaning one or more sensitive operations are exposed without verifying caller identity. Per the CPE 'cpe:2.3:a:akin_software_computer_import_export_industry_and_trade_ltd.:cafeplus', the flaw lives in the application layer, and the CVSS adjacent-network vector (AV:A) implies the exposed function is reachable over LAN/Wi-Fi rather than the public internet, consistent with a thick-client or LAN service architecture typical of POS suites.
RemediationAI
Upgrade CafePlus to version 12.05.04 or later, which the advisory metadata indicates is the fixed release; confirm availability and patch notes via the vendor through the TR-CERT bulletin at https://siberguvenlik.gov.tr/guvenlik-bildirimleri/detay/tr-26-0428. Until patched, segment CafePlus servers and terminals onto a dedicated management VLAN isolated from guest Wi-Fi and untrusted staff devices to neutralize the adjacent-network vector (trade-off: requires switch/AP capable of VLAN tagging and may break ad-hoc tablet ordering setups). Additionally, restrict access to CafePlus listening ports with host-based firewall rules permitting only known POS terminal IPs (trade-off: breaks dynamic DHCP terminal deployments) and monitor LAN traffic for anomalous connections to the CafePlus service.
