Eclipse Jetty's HTTP/1.1 parser improperly handles unclosed quoted strings in chunked transfer encoding extensions, enabling request smuggling attacks that can lead to injection of smuggled requests, cache poisoning, and unauthorized access.
Apache MINA's AbstractIoBuffer.resolveClass() vulnerability allows remote attackers to bypass classname validation and execute arbitrary code, affecting Oracle Middleware and Enterprise Manager products with critical severity.
Apache Log4j versions 2.13.1 through 2.25.4 and 2.26.0 have vulnerabilities including improper JSON encoding of non-finite floating-point values and potential data modification risks, affecting Oracle products such as Autonomous Health Framework and Enterprise Manager with varying exploitability and severity.
A vulnerability in Oracle Enterprise Manager Base Platform versions 13.5 and 24.1 allows a low-privileged attacker with network access via SOAP to compromise the system, with a CVSS 3.1 base score of 6.5.
A vulnerability in Oracle Enterprise Manager for Oracle Database 24.1 allows a low-privileged attacker with HTTP network access to gain unauthorized access to critical data, with a CVSS 3.1 base score of 7.7.
A critical unauthenticated remote code execution vulnerability in Oracle Enterprise Manager for Fusion Middleware (versions 13.5 and 24.1) has a CVSS 3.1 base score of 9.8, severely impacting confidentiality, integrity, and availability.

"category": "description",
"text": "De kwetsbaarheden betreffen verschillende beveiligingsproblemen in Oracle Enterprise Manager-producten, waaronder mogelijkheden voor niet-geauthenticeerde en laaggeprivilegieerde kwaadwillenden om via netwerktoegang ongeautoriseerde acties uit te voeren. De kwetsbaarheden hebben CVSS-scores vari\u00ebrend van middel tot kritiek. Van de in totaal 7 kwetsbaarheden zijn drie als kritiek aangemerkt en volgens Oracle kunnen vijf kwetsbaarheden zonder authenticatie op afstand worden misbruikt. Succesvol misbruik kan onder meer leiden tot het verkrijgen van ongeautoriseerde toegang tot gevoelige informatie, het wijzigen van gegevens en het verstoren van de beschikbaarheid van getroffen systemen. Sommige kwetsbaarheden vereisen voorafgaande toegangsrechten, terwijl andere volledig op afstand en zonder authenticatie kunnen worden misbruikt.\n\nDe drie kwetsbaarheden die als kritiek zijn aangemerkt, CVE-2026-41635, CVE-2026-83355 en CVE-2026-2332, hebben een CVSS-score van 9,1 of hoger en bevinden zich in Agent Next Gen van Oracle Enterprise Manager Base Platform, Metrics van Oracle Enterprise Manager for Fusion Middleware en de Oracle Management Service (OMS) van Oracle Enterprise Manager Base Platform. Deze kwetsbaarheden kunnen volgens Oracle zonder authenticatie op afstand worden misbruikt, vereisen een lage aanvalscomplexiteit en geen gebruikersinteractie. Succesvolle exploitatie kan een hoge impact hebben op de vertrouwelijkheid en integriteit en,ook op de beschikbaarheid van getroffen systemen.\n\nHet NCSC adviseert om de beveiligingsupdates voor de kritieke kwetsbaarheden met voorrang toe te passen.",
