Wilmington, DE —4 May 2021—
Who: Apache OpenOffice, an Open Source office-document productivity suite comprising six productivity applications: Writer, Calc, Impress, Draw, Math, and Base. The OpenOffice suite is based around the OpenDocument Format (ODF), supports 41 languages, and ships for Windows, macOS, Linux 64-bit, and Linux 32-bit. Apache OpenOffice delivers up to 2.4 Million downloads each month.
What: A recently reported vulnerability states that all versions of OpenOffice through 4.1.9 can open non-http(s) hyperlinks, and could lead to untrusted code execution.
The Apache OpenOffice Project has filed a Common Vulnerabilities and Exposures report with MITRE Corporation’s national vulnerability reporting system:
> CVE-2021-30245: Code execution in Apache OpenOffice via non-http(s) schemes in Hyperlinks
> Severity: moderate
>Credit: Fabian Bräunlein and Lukas Euler of Positive Security https://positive.security/blog/url-open-rce#open-libreoffice
The complete CVE report is available at https://www.openoffice.org/security/cves/CVE-2021-30245.html
How: Applications of the OpenOffice suite handle non-http(s) hyperlinks in an insecure way, allowing for 1-click code execution on Windows and Xubuntu systems via malicious executable files hosted on Internet-accessible file shares.
Why: The mitigation in Apache OpenOffice 4.1.10 assures that a security warning is displayed to give users the option of continuing to open the hyperlink. Best practice dictates to be careful when opening documents from unknown and unverified sources.
When: The vulnerability predates OpenOffice entering the Apache Incubator. During the analysis of this issue, it was discovered that an incorrect bug fix was made by the StarOffice/OpenOffice.org developers preparing OpenOffice 2.0 in 2005, whilst under the auspices of Sun Microsystems.
