Summary
Na dotkniętych platformach z obsługą sprzętowego IPSec działających na Arista EOS z włączonymi określonymi funkcjami IPsec, EOS może wykazywać nieoczekiwane zachowanie w określonych przypadkach. Fluktuacje interfejsów fizycznych oraz niektóre restarty agentów mogą powodować ponowne nawiązywanie tunelu IPsec z istniejącymi skojarzeniami bezpieczeństwa, co prowadzi do niezgodności numerów sekwencyjnych między punktami końcowymi tunelu.
Risk Assessment
Niezgodności numerów sekwencyjnych mogą prowadzić do niestabilnej komunikacji, co może wpłynąć na integralność i dostępność usług w organizacji. W przypadku krytycznych aplikacji, może to prowadzić do poważnych zakłóceń w działaniu systemów.
Recommendation
Zaleca się monitorowanie i aktualizację konfiguracji IPsec w Arista EOS, aby zminimalizować ryzyko wystąpienia fluktuacji interfejsów oraz niezgodności numerów sekwencyjnych. Warto również rozważyć wdrożenie dodatkowych mechanizmów zabezpieczających dla stabilności komunikacji.

- CVE-2026-101117Critical
IBM WebSphere Extreme Scale versions 8.6.1.0 through 8.6.2.2 have an improper Content Security Policy configuration that could allow a remote attacker to bypass security restrictions. The flaw concerns browser-side protection mechanisms.
- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
On affected platforms with hardware IPSec support running Arista EOS with certain IPsec features enabled, EOS may exhibit unexpected behavior in specific cases. Physical interface flaps and certain agent restarts can cause IPsec tunnel re-establishment with existing Security Associations, resulting in sequence number mismatches between tunnel endpoints potentially causing unstable communication.
