Detailsinfo

A vulnerability has been found in bestpractical rt up to 5.0.9/6.0.2 and classified as problematic. This vulnerability affects an unknown code. The manipulation with an unknown input leads to a csv injection vulnerability. The CWE definition for the vulnerability is CWE-1236. The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

RT is an open source, enterprise-grade issue and ticket tracking system. Versions prior to 5.0.10 and 6.0.0 through 6.0.2 contain a spreadsheet (CSV/formula) injection vulnerability. User-controlled data in spreadsheet exports is not sanitized before being written to the output file, which can cause spreadsheet applications to interpret crafted values as formulas or macros when the file is opened. This issue has been fixed in versions 5.0.10 and 6.0.3. If developers are unable to upgrade immediately, they can temporarily work around this issue by avoiding opening exported RT spreadsheet files directly in spreadsheet applications when the data may contain untrusted user input.
