The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein. NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory. This security advisory is subject to Dutch law.

Feiten: Oracle heeft kwetsbaarheden verholpen in Communications producten en onderliggende third party software. Het betreft een totaal van 213 kwetsbaarheden, waarvan 67 zich bevinden in Oracle producten en 146 in third-party producten waar eerder updates voor zijn verschenen en welke in deze Oracle updates zijn verwerkt.
Interpretaties: De ernstigste kwetsbaarheden, 12 stuks, hebben een CVSS score van 9 en hoger gekregen en zijn hieronder omschreven. 11 hiervan bevinden zich in embedded third-party producten. De overige kwetsbaarheden hebben lagere scores gekregen en het voert te ver om detailinformatie op te nemen in deze advisory. Hiervoor verwijst het NCSC naar de bijgevoegde referentie. Oracle Communications Converged Application Server versies 8.2 en 8.3 bevatten een kwetsbaarheid die onbevoegde netwerktoegang mogelijk maakt en kan leiden tot volledige overname van het systeem. Libtiff tot versie 4.7.0 bevat een write-what-where kwetsbaarheid en een stack-based buffer overflow die kunnen worden geactiveerd door speciaal vervaardigde TIFF-bestanden, wat kan leiden tot code-executie of crashes. Apache Tomcat versies 8.5.0 tot 11.0.5 bevatten kwetsbaarheden waardoor speciaal opgemaakte HTTP-verzoeken rewrite rules en security constraints kunnen omzeilen, met mogelijke data disclosure, wijziging of denial of service als gevolg. Eclipse Jetty's HTTP/1.1 parser verwerkt chunked transfer encoding extensies met onjuist gesloten aanhalingstekens verkeerd, wat request smuggling mogelijk maakt en kan leiden tot cache poisoning, access control bypass en sessie kaping. Perl versies met een verouderde vendored zlib in Compress::Raw::Zlib bevatten meerdere beveiligingsproblemen die zijn opgelost in een specifieke commit. Lodash versies tot 4.17.23 bevatten meerdere kwetsbaarheden waaronder code-injectie via onbetrouwbare keys in _.template, prototype pollution, regex denial of service en command injection. Apache HTTP Server versies 2.4.0 tot 2.4.67 bevatten diverse kwetsbaarheden in meerdere modules die kunnen leiden tot server crashes, code-executie, cross-site scripting en informatielekken. Apache Kafka versies 4.1.0 en 4.1.1 hebben een kwetsbaarheid in de JWT token validatie waardoor onbevoegde toegang mogelijk is. AIOHTTP versies voor 3.13.4 accepteren null bytes en control characters in HTTP headers, wat header injectie en response splitting mogelijk maakt. De cryptography package van versies 45.0.0 tot 46.0.7 bevat een buffer overflow bij het verwerken van niet-contigu buffers op Python 3.11+, wat kan leiden tot crashes of informatielekken. Spring Boot versies 4.0.0 tot 4.0.5 bevatten een kwetsbaarheid die het mogelijk maakt om de standaard web security te omzeilen. Apache MINA versies 2.1.X en 2.2.X bevatten meerdere deserialisatie kwetsbaarheden die code-executie mogelijk maken door bypass van classname allowlist en filters.
Oplossingen: Oracle heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Gebruikers wordt geadviseerd de relevante updates te installeren. Zie bijgevoegde referenties voor meer informatie.
