AQSh kiberxavfsizlik agentligi CISA chorshanba kuni xakerlar VMware ESXi zaifligini hujumlarda ishlatayotganini ogohlantirdi.
CVE-2026-41709 sifatida kuzatilgan zaiflik past darajadagi jurnalga yozish yetarli emasligi muammosi sifatida tavsiflanadi. U ma'mur sifatida tizimga kirgan hujumchilarga ba'zi operatsiyalarni jurnalga yozmasdan bajarishga imkon beradi.
Xavfsizlik nuqsoni 29-iyulda VMware vCenter, ESXi, Workstation va Fusion'dagi uchta muhim va bitta yuqori darajadagi xato bilan birga e'lon qilingan.
VMware ESXi-9.1.0.0-25370933, ESXi-9.0.2.0100-25595025 va ESXi80U3j-25429389 va undan yangi versiyalarda tegishli tuzatishlar mavjud.
CISA CVE-2026-41709 ni Ma'lum Ishlatilgan Zaifliklar (KEV) katalogiga qo'shib, federal agentliklarni uni keyingi ikki hafta ichida tuzatishga chaqirdi.
CISA kuzatilgan ishlatish haqida tafsilotlar bermadi, ammo CrowdStrike chorshanba kuni Xitoy bilan bog'liq Warp Panda tahdid aktori CVE-2026-41709 ni AQSh tashkilotlari, jumladan yuridik firmalar, hujumlarida nol kun zaifligi sifatida ishlatganini xabar qildi.
Reklama. O'qishni davom ettirish uchun pastga aylantiring.
CrowdStrike ma'lumotiga ko'ra, Warp Panda odatda internetga ochiq chekka qurilmalar orqali dastlabki kirishni oladi va VMware vCenter'ga o'tadi, u yerda 2025-yil davomida BrickStorm, TetanusStorm, SharpStorm, DualGauge va GuestConduit kabi zararli dasturlarni joylashtirgan.
Ushbu hujumlarning bir nechtasida va 2026-yil boshigacha, guruh CVE-2026-41709 dan audit izini sezilarli darajada kamaytirish uchun foydalangan.
Broadcom'ning 29-iyuldagi maslahatlarida tasvirlangan kamida yana ikkita xavfsizlik nuqsoni yovvoyi tabiatda nishonga olingan, ya'ni CVE-2026-59309 (muhim darajadagi autentifikatsiya chetlab o'tish) va CVE-2026-59310 (muhim katalog o'tish muammosi, ixtiyoriy kod bajarilishiga olib keladi).
Avgust o'rtalarida kiberxavfsizlik kompaniyasi Quirso APT CVE-2026-59310 ni taxminan 360 ta veb orqali kirish mumkin bo'lgan VMware vCenter serverlarini buzish va SSH teskari qobiqni joylashtirish uchun ishlatayotganini aytdi.
Keyinchalik Quirso faoliyatni Xitoy bilan bog'liq tahdid aktoriga bog'ladi va CVE-2026-59309 ham ishlatilganini, ehtimol CVE-2026-59310 dan oldin, ehtimol boshqa tahdid aktori tomonidan ishlatilganini ogohlantirdi.
CVE-2026-59310 ning ommaviy nishonga olinishi sentabr boshida e'lon qilindi.

Chinese Hackers Quietly Used Low-Severity ESXi Logging Flaw as Zero-Day
CVE-2026-41709 allows attackers with administrative privileges to perform operations without being logged.

The US cybersecurity agency CISA on Wednesday warned that hackers have been exploiting another VMware ESXi vulnerability in attacks.
Tracked as CVE-2026-41709, the exploited flaw is described as a low-severity insufficient logging issue. It allows attackers logged in as administrators to perform certain operations without being logged.
The security defect was disclosed on July 29 alongside three critical and one high-severity bug in VMware vCenter, ESXi, Workstation, and Fusion.
VMware ESXi-9.1.0.0-25370933, ESXi-9.0.2.0100-25595025, and ESXi80U3j-25429389 and newer releases contain the relevant patches.
CISA added CVE-2026-41709 to its Known Exploited Vulnerabilities (KEV) catalog, urging federal agencies to patch it within the next two weeks.
CISA did not provide details on the observed exploitation, but CrowdStrike reported on Wednesday that the China-nexus threat actor Warp Panda had exploited CVE-2026-41709 as a zero-day in intrusions at US organizations, including law firms.

According to CrowdStrike, Warp Panda typically gains initial access through internet-facing edge devices and pivots to VMware vCenter, where it deployed malware such as BrickStorm, TetanusStorm, SharpStorm, DualGauge and GuestConduit in intrusions throughout 2025.
In several of those attacks, and as late as early 2026, the group used CVE-2026-41709 to significantly reduce audit trail visibility.
At least two other security defects described in Broadcom’s July 29 advisories have been targeted in the wild, namely CVE-2026-59309 (a critical-severity authentication bypass) and CVE-2026-59310 (a critical directory traversal issue leading to arbitrary code execution).
In mid-August, cybersecurity company Quirso said an APT had been exploiting CVE-2026-59310 to compromise approximately 360 web-accessible VMware vCenter servers and deploy an SSH reverse shell.
Later, Quirso attributed the activity to a China-linked threat actor and warned that CVE-2026-59309 had been exploited as well, likely before CVE-2026-59310, potentially by a different threat actor.
Mass targeting of CVE-2026-59310 was flagged in early September.
