Kwetsbaarheden verholpen in Rsync

Notes

The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions: NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. 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. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten
Rsync Project heeft kwetsbaarheden verholpen in Rsync (versies <3.4.0).
Interpretaties
De meest kritieke kwetsbaarheden in Rsync omvatten een heap-gebaseerde 'buffer overflow' (CVE-2024-12084) en een 'info leak' (CVE-2024-12085) die kunnen leiden tot willekeurige code-executie (aanwezig in Rsync-versies 3.2.7 & 3.3.0). Daarnaast zijn er kwetsbaarheden gerelateerd aan 'path traversal' en onjuiste verificatie van symbolische links, wat kan leiden tot ongeautoriseerde toegang tot gevoelige gegevens en het schrijven van bestanden buiten de bedoelde directory. Deze kwetsbaarheden kunnen worden misbruikt door aanvallers om de beschikbaarheid, integriteit en vertrouwelijkheid in gevaar te brengen. Gezien de bekendheid van Rsync en de brede implementatie verwacht het NCSC op korte termijn PoC code.
Oplossingen
Rsync Project heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
