Een kwaadwillende met geldige inloggegevens voor een alternatieve authenticatiemethode kan de kwetsbaarheid op afstand misbruiken om de SAML-authenticatie te omzeilen. Hierdoor kan ook multifactorauthenticatie (MFA), die via SAML wordt afgedwongen, worden omzeild. SonicWall heeft onderzoek gedaan naar meldingen van mogelijk actief misbruik. Inmiddels is de kwetsbaarheid ook opgenomen in de Known Exploited Vulnerabilities-catalogus van CISA.\n\nDe kwetsbaarheden met kenmerken CVE-2026-107154 en CVE-2026-107155 hebben beide een CVSS-score van 8.8 en betreffen respectievelijk een fout in de sessievalidatie en een onjuist beveiligd cross-domain-beleid in de beheerinterface van SonicOS. Een niet-geauthenticeerde kwaadwillende kan deze kwetsbaarheden onder specifieke omstandigheden op afstand misbruiken om ongeautoriseerde handelingen uit te voeren. Hierbij is wel gebruikersinteractie vereist.\n\nDe kwetsbaarheid met kenmerk CVE-2026-82308 heeft een CVSS-score van 7.5 en betreft een heap-based buffer overflow in de SSL-VPN-functionaliteit. Een niet-geauthenticeerde kwaadwillende kan deze kwetsbaarheid op afstand misbruiken om een Denial-of-Service (DoS) te veroorzaken.\n\nDe overige drie kwetsbaarheden betreffen twee buffer-overflows in de TACACS+-authenticatiefunctionaliteit en een zwakke wachtwoordhashing op virtuele SonicOS-appliances. Misbruik van de buffer-overflows kan leiden tot verstoring van de dienstverlening. De zwakke wachtwoordhashing kan een kwaadwillende met bestaande lokale toegang in staat stellen een platformcredential te achterhalen.", "title": "Interpretaties" }, { "category": "description", "text": "SonicWall heeft updates uitgebracht om de kwetsbaarheden in SonicOS te verhelpen.
