DescriptionNVD

An unauthenticated remote attacker can read memory out of bounds due to improper input validation in the MQTT stack. The brute force attack is not always successful because of memory randomization.

AnalysisAI

An unauthenticated remote attacker can read memory out of bounds due to improper input validation in the MQTT stack. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. An unauthenticated remote attacker can read memory out of bounds due to improper input validation in the MQTT stack. The brute force attack is not always successful because of memory randomization. Affected products include: Phoenixcontact Charx Sec-3000 Firmware, Phoenixcontact Charx Sec-3050 Firmware, Phoenixcontact Charx Sec-3100 Firmware, Phoenixcontact Charx Sec-3150 Firmware.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
