The following Zyxel goods are impacted –
- USG/ZyWALL working firmware versions ZLD V4.20 by ZLD V4.70 (set in ZLD V4.71)
- USG FLEX jogging firmware versions ZLD V4.50 via ZLD V5.20 (mounted in ZLD V5.21 Patch 1)
- ATP operating firmware versions ZLD V4.32 through ZLD V5.20 (fastened in ZLD V5.21 Patch 1)

CISA warns about actively exploited Sophos and Development Micro flaws
The disclosure arrives as equally Sophos and SonicWall launched patches this 7 days to their firewall appliances to take care of critical flaws (CVE-2022-1040 and CVE-2022-22274) that could enable a distant attacker to execute arbitrary code on impacted methods.
The critical Sophos firewall vulnerability, which has been observed exploited in lively attacks versus select companies in South Asia, has given that been additional by the U.S. Cybersecurity and Infrastructure Security Company (CISA) to its Identified Exploited Vulnerabilities Catalog.
Also included to the listing is a superior-severity arbitrary file upload vulnerability in Trend Micro’s Apex Central solution that could permit an unauthenticated remote attacker to add an arbitrary file, resulting in code execution (CVE-2022-26871, CVSS score: 8.6).
“Craze Micro has observed an active attempt of exploitation in opposition to this vulnerability in-the-wild (ITW) in a incredibly minimal variety of occasions, and we have been in get hold of with these prospects by now,” the business stated. “All consumers are strongly encouraged to update to the newest model as quickly as possible.”
