causefx/organizr: Improper Neutralization of Input During Web Page Generation
CVE-2022-1344 is a critical-severity improper neutralization of input during web page generation vulnerability in causefx/organizr from Causefx, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 2.1.1810 as the first without the flaw, so updating causefx/organizr to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.04% chance of exploitation within 30 days, higher than 65% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update causefx/organizr to 2.1.1810 or a later version.
- Update Organizr to 2.1.1810 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Stored XSS due to no sanitization in the filename in GitHub repository causefx/organizr prior to 2.1.1810. This allows attackers to execute malicious scripts in the user's browser and it can lead to session hijacking, sensitive data exposure, and worse.

The underlying weakness: Improper Neutralization of Input During Web Page Generation
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
- Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
