Zaifliklar
Yangi WordPress zaifligi hujumchilarning nishonida
Tahdid ishtirokchilari yangi yuqori darajadagi WordPress zaifligini tuzatishlar tarqatilgandan bir necha soat ichida ekspluatatsiya qilishga urinishni boshladilar, deb ogohlantiradi Defiant.
28-oktabrda WordPress 7.1.4 da tuzatilgan xavfsizlik nuqsoni WordPress yangilash jarayoniga ta'sir qiladi va masofaviy kod bajarish uchun ekspluatatsiya qilinishi mumkin.
Defiant ma'lumotiga ko'ra, bu WordPress Core yangilash jarayonidagi poyga sharti (race condition) bo'lib, autentifikatsiyasiz ekspluatatsiya qilinishi mumkin. Biroq hujum murakkabligi yuqori. Zaiflikka hali CVE identifikatori berilmagan.
Zaiflik yangilanishlar paytida bashorat qilinadigan, veb orqali kirish mumkin bo'lgan tayyorlash yo'llaridan kelib chiqadi. Yangi fayllar ko'plab serverlarda vebdan kirish mumkin bo'lgan bashorat qilinadigan katalogga ochiladi.
"Hujumchiga o'rnatuvchi fayllarni o'z ichiga olgan to'liq paket yangilanishi, tayyorlash daraxtiga veb va PHP kirishi, bashorat qilinadigan yoki aniqlangan tayyorlash yo'li, shuningdek WordPress vaqtinchalik fayllarni tozalashdan oldin hujumni yakunlash uchun yetarli vaqt kerak," deb tushuntiradi Defiant.
Veb-xavfsizlik firmasi ma'lumotiga ko'ra, tahdid ishtirokchilari allaqachon zaiflikni ekspluatatsiya qilishga urinishmoqda, zaif yo'llarni qayta-qayta tekshirish orqali soniyalar davom etadigan ekspluatatsiya oynasiga urinishmoqda.

Hujumchi zaiflikni ekspluatatsiya qilish uchun saytda hisob qaydnomasiga ega bo'lishi shart emas, lekin ular "WordPress to'liq Core yangilanishini ochayotganda juda tor oynaga urishlari" kerak, deydi Defiant.
Xavfsizlik xatosini bartaraf etish uchun WordPress endi tayyorlash katalogini tasodifiylashtiradi, indeks himoyasini qo'shadi va tayyorlangan konfiguratsiya ma'lumotlarini xavfsiz ravishda ilgari surishni oldini oladi.
"Wordfence telemetriyasi shuni ko'rsatadiki, tahdid ishtirokchilari allaqachon zaiflikni faol ravishda ekspluatatsiya qilishga urinishmoqda. Yangi xavfsizlik devori qoidamiz joylashtirilgandan to'qqiz daqiqa o'tib birinchi moslik qayd etildi. Birinchi 21 soat ichida tayyorlangan setup-config.php o'rnatuvchi yo'llariga qaratilgan 18 500 dan ortiq so'rov qayd etildi," deydi Defiant.
Wordfence muvaffaqiyatli buzilishlar haqida xabar bermagan.
Zaiflik uchun tuzatishlar WordPress 7.1.4 ga kiritilgan va WordPress 4.7 gacha bo'lgan tarmoqlarga orqaga moslashtirilgan.
WordPress 7.1.4 22 ta xavfsizlik nuqsoni, jumladan bir nechta XSS zaifliklari, interaktivlik API muammolari, autentifikatsiyasiz ma'lumot oshkor qilish xatosi va avtorizatsiya zaifligi uchun tuzatishlarni o'z ichiga oladi, shuningdek yaqinda eMudhra bekor qilinishini aks ettirish uchun ildiz sertifikatlarini yangilaydi.

Fresh WordPress Vulnerability in Attackers’ Crosshairs
Threat actors are attempting to exploit a high-severity unauthenticated race condition leading to remote code execution.

Threat actors started exploiting a new high-severity WordPress vulnerability within hours of patches rolling out, Defiant warns.
Patched on October 28 in WordPress 7.1.4, the security defect impacts the WordPress update process and can be exploited for remote code execution.
According to Defiant, it is a race condition in WordPress’s Core update process that can be exploited without authentication. The attack complexity, however, is high. No CVE identifier has been assigned to the vulnerability yet.
The weakness stems from predictable, web-accessible staging paths during the upgrades. New files are unpacked into a predictable directory that is accessible from the web on many servers.
“The attacker needs a full-package update containing the installer files, public web and PHP access to the staging tree, a predictable or discovered staging path, and enough time to complete the attack before WordPress cleans up the temporary files,” Defiant explains.
According to the web security firm, threat actors are already attempting to exploit the vulnerability, polling the vulnerable paths repeatedly in their attempts to hit the seconds-long exploitability window.

While an attacker does not need an account on the site to exploit the flaw, they do need “to hit a very narrow window while WordPress is unpacking a complete Core update,” Defiant says.
To address the security bug, WordPress now randomizes the staging directory, adds an index guard, and prevents the unsafe promotion of staged configuration data.
“Wordfence telemetry shows that threat actors are already actively attempting to exploit the vulnerability. The first match for our new firewall rule arrived nine minutes after deployment. During the first 21 hours, we recorded more than 18,500 requests targeting staged setup-config.php installer paths,” Defiant says.
Wordfence has not reported successful compromises.
Fixes for the vulnerability were included in WordPress 7.1.4 and backported to branches through WordPress 4.7.
WordPress 7.1.4 includes patches for 22 security defects, including several XSS flaws, interactivity API issues, an unauthenticated information disclosure bug, and an authorization weakness, and also updates the bundled root certificates to reflect the recent eMudhra revocation.
