CVE-2019-15302

The pad management logic in XWiki labs CryptPad before 3.0.0 allows a remote attacker (who has access to a Rich Text pad with editing rights for the URL) to corrupt it (i.e., cause data loss) via a trivial URL modification.

Weakness

The product does not release or incorrectly releases a resource before it is made available for re-use.

Affected Software

Potential Mitigations

• Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
• For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
