**Name of the Vulnerable Software and Affected Versions** QNAP VioStor NVR models running QVR Firmware versions prior to 5.0.0 **Description** An OS command injection vulnerability has been found to affect legacy QNAP VioStor NVR models. If exploited, the vulnerability could allow authenticated users to execute commands via a network. The vulnerability exists due to the lack of measures to neutralize special elements. It is reported that the vulnerability has been exploited in the wild. Approximately 27,804 devices are potentially affected, mainly distributed in Japan, Mexico, and other countries. **Recommendations** For QVR Firmware versions prior to 5.0.0, update to QVR Firmware 5.0.0 or later to resolve the issue. As a temporary workaround, consider restricting network access to the vulnerable devices until a patch is applied. Avoid using the vulnerable QVR Firmware versions until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** FXC AE1021 firmware version 2.0.9 and earlier FXC AE1021PE firmware version 2.0.9 and earlier **Description** An OS command injection vulnerability exists, allowing an attacker who can log in to the product to execute arbitrary OS commands. The vulnerability is related to the lack of measures to neutralize special elements used in the OS command. Exploitation of this vulnerability may allow a remote attacker to execute arbitrary commands. New botnet malware has been found to exploit this flaw in routers. **Recommendations** For FXC AE1021 firmware version 2.0.9 and earlier, update to a version later than 2.0.9 to resolve the issue. For FXC AE1021PE firmware version 2.0.9 and earlier, update to a version later than 2.0.9 to resolve the issue. As a temporary workaround, consider restricting access to the product to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** IBM Security Access Manager for Web versions 7.0.0 through 7.0.0 FP11 IBM Security Access Manager for Web versions 8.0.0 through 8.0.1 FP0 **Description** The issue concerns the Multicast DNS (mDNS) responder, which responds to unicast queries with source addresses that are not link-local. This allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets. **Recommendations** For IBM Security Access Manager for Web versions 7.0.0 through 7.0.0 FP11, update to version 7.0.0 FP12. For IBM Security Access Manager for Web versions 8.0.0 through 8.0.1 FP0, update to version 8.0.1 FP1.

**Name of the Vulnerable Software and Affected Versions** Synology DiskStation Manager (DSM) versions prior to 3.1 **Description** The issue allows remote attackers to cause a denial of service or obtain potentially sensitive information via port-5353 UDP packets to the Avahi component. This is due to the Multicast DNS (mDNS) responder inadvertently responding to unicast queries with source addresses that are not link-local. **Recommendations** For versions prior to 3.1, update to version 3.1 or later to resolve the issue. As a temporary workaround, consider restricting access to port 5353 to minimize the risk of exploitation.
