De kwetsbaarheden bevinden zich in de managementinterface van AOS-S en maken het mogelijk voor een niet-geauthenticeerde externe aanvaller om authenticatiecontroles te omzeilen en toegang te verkrijgen tot het systeem. Voor CVE-2026-76743 geldt dat deze alleen te misbruiken is onder door HPE niet gespecificeerde randvoorwaarden.\n\nDe kwetsbaarheid met kenmerk CVE-2026-76744 heeft een CVSS-score van 9.8. Het betreft een buffer overflow die door een niet-geauthenticeerde externe aavaller misbruikt kan worden om willekeurige code uit te voeren op het getroffen systeem.\n\nDe kwetsbaarheid met kenmerk CVE-2026-76745 heeft een CVSS-score van 9.6. Wanneer een een ongeauthenticeerde aanvaller vanuit een aangrenzend netwerk deze fout misbruikt kan dit leiden tot geheugen corruptie en het uitvoeren van willekeurige code op het getroffen systeem.\n\nDe kwetsbaarheid met kenmerk CVE-2026-76746 heeft een CVSS-score van 9.3. Het betreft een buffer overflow die door een niet-geauthenticeerde aanvaller vanuit een aangrenzend netwerk misbruikt kan worden en kan leiden tot het lekken van gevoelige informatie of het veroorzaken van een denial of service op het getroffen systeem.\n\nDe kwetsbaarheid met kenmerk CVE-2026-76747 heeft een CVSS-score van 9.1. Het betreft een buffer overflow die door een niet-geauthenticeerde externe aanvaller misbruikt kan worden. Misbruik van deze fout kan leiden tot het lekken van gevoelige informatie of denial of service op het getroffen systeem.\n\nDe succesvolle exploitatie van deze kwetsbaarheden kan de vertrouwelijkheid, integriteit en beschikbaarheid van het getroffen systeem beïnvloeden.",
