Summary
Kwetsbaarheden verholpen in IBM Aspera High-Speed Transfer Endpoint en Server
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: IBM heeft kwetsbaarheden verholpen in IBM Aspera High-Speed Transfer Endpoint en Server versies 3.7.4 tot en met 4.4.7 Fix Pack 1.
Interpretaties: De kwetsbaarheden bevinden zich in de asperahttpd component van de IBM Aspera High-Speed Transfer Endpoint en Server producten. Een buffer overflow kan leiden tot Denial-of-Service, omzeilen van authenticatie, of het uitvoeren van willekeurige code op afstand. Een niet-geauthenticeerde aanvaller kan de asperahttpd service laten crashen, wat resulteert in een serviceonderbreking. Daarnaast kan een geauthenticeerde gebruiker de normale autorisatiemechanismen omzeilen en lokaal opgeslagen bestanden op de server lezen zonder toestemming. Deze kwetsbaarheden zijn aanwezig in meerdere versies binnen het genoemde bereik.
Oplossingen: IBM heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
