Jamovi 0955 Exploit __link__ -
Affects versions ≤ 1.6.18; allows malicious payloads via column names. HTB Scenario
It is well-documented in walkthroughs for the "Talkative" machine on HackTheBox. Safety for Real Data Not Recommended
The attacker takes a legitimate .omv statistical data file and changes its extension to .zip to extract the internal directory structure.
The exploit in question was discovered by a researcher who noticed that jamovi 0.9.5.5 was vulnerable to a specific type of attack. The exploit allows an attacker to manipulate the data being analyzed in jamovi, effectively allowing them to alter the results of statistical analyses. This is particularly concerning, as it could lead to incorrect conclusions being drawn from data. jamovi 0955 exploit
Jamovi is a legitimate open-source statistical software package (based on R) used for data analysis, and “0955” does not correspond to a recognized version number (e.g., recent stable versions are 2.3, 2.4, 2.5). It’s possible that:
: The JS uses jamovi's internal API to send commands to the R engine, effectively escaping the "sandbox." ⚠️ Current Status & Mitigation Patched : This issue was addressed in version 0.9.5.6 .
The attacker modifies the name value of one or more columns, replacing it with a malicious JavaScript payload. For example: Affects versions ≤ 1
jamovi’s is a plugin that allows users to write and execute arbitrary R language code. While this is a legitimate feature for advanced analysis, it becomes a security hole when jamovi is exposed on a network without proper authentication.
By carefully crafting a data set, an attacker can manipulate the PRNG to produce a specific sequence of numbers that, when used in a statistical analysis, will produce a desired result. This can include producing artificially significant p-values, inflating or deflating effect sizes, or even creating fake data that appears to support a specific hypothesis.
: Version 0.9.5.5 dates back several years. Modern security patches, including the fix for the Electron-based XSS, were only introduced in versions released after April 2021 (Version 1.6.19 and later). Availability of PoCs The exploit in question was discovered by a

The Jamovi 0.9.5.5 exploit works by taking advantage of the software's reliance on algorithms to process data. Specifically, the exploit targets the software's use of pseudorandom number generators (PRNGs) to generate random numbers for statistical analyses.
