AI Analysis

Impact

The vulnerability exists in the Oracle Hospitality Simphony POS component. An unauthenticated attacker with network access via HTTP can compromise the system, allowing the attacker to create, delete, or modify critical data. The flaw also enables an attacker to cause the system to hang or repeatedly crash, resulting in a complete denial of service. The CVSS vector indicates the attack requires network access, no authentication, and no user interaction, with high integrity and availability impacts.

Affected Systems

The affected product is Oracle Hospitality Simphony, versions 19.8‑19.8.5, 19.9‑19.9.3, and 19.10‑19.10.1 from Oracle Corporation.

Risk and Exploitability

The CVSS base score of 9.1 signifies high severity. The EPSS score listed is below 1%, indicating a low probability of exploitation, and the vulnerability is not yet listed in the CISA KEV catalog. The attacker only needs network connectivity to the POS HTTP interface; authentication is not required. Given the low EPSS probability but high impact, the risk remains significant.
