Official description
Dell Multifunction Printer E525w Driver and Software Suite, versions prior to 1.047.2022, A05, contain a local privilege escalation vulnerability that could be exploited by malicious users to compromise the affected system
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Unquoted Search Path or Element
The product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. This can cause the product to access resources in a parent path.
How developers prevent this class of flaw
- Properly quote the full search path before executing a program on the system.
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
