Most Affected Products
A stored cross-site scripting (XSS) vulnerability in the Forums module of Tendenci CMS v15.3.7 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload.
A stored cross-site scripting (XSS) vulnerability in the Jobs module of Tendenci CMS v15.3.7 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload.
Tendenci 12.3.1 contains a CSV formula injection vulnerability in the contact form message field that allows attackers to inject malicious formulas during export. Attackers can submit crafted payloads like '=10+20+cmd|' /C calc'!A0' in the message field to trigger arbitrary command execution when the CSV is opened in spreadsheet applications.
Tendenci is an open source content management system built for non-profits, associations and cause-based sites. Versions 15.3.11 and below include a critical deserialization vulnerability in the Helpdesk module (which is not enabled by default). This vulnerability allows Remote Code Execution (RCE) by an authenticated user with staff security level due to using Python's pickle module in helpdesk /reports/. The original CVE-2020-14942 was incompletely patched. While ticket_list() was fixed to use safe JSON deserialization, the run_report() function still uses unsafe pickle.loads(). The impact is limited to the permissions of the user running the application, typically www-data, which generally lacks write (except for upload directories) and execute permissions. This issue has been fixed in version 15.3.12.
Tendenci 12.0.10 allows unrestricted deserialization in apps\helpdesk\views\staff.py.
Multiple cross-site scripting (XSS) vulnerabilities in search.asp in Tendenci CMS allow remote attackers to inject arbitrary web script or HTML via the (1) category, (2) searchtext, (3) jobcategoryid, (4) contactcompany, and unspecified other parameters. NOTE: some of these details are obtained from third party information. NOTE: it is not clear whether this affects Tendenci Enterprise Edition in addition to the product's deployment on Tendenci's own server farm. If only the latter was affected, then this issue should not be included in CVE.
