A vulnerability was found in CallBackery up to 0.61.x. It has been rated as critical. This issue affects the function createRxValidator of the component Regex Validation. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
CallBackery versions before 0.62.0 for Perl accept unintended values in form fields checked by createRxValidator. createRxValidator() is documented to anchor the supplied pattern at both ends, but builds /^${rx}$/ without grouping the pattern. An alternation such as yes|no then accepts any value starting with yes or ending with no, and $ also accepts a value with one trailing newline. An authenticated user can submit values the pattern was meant to reject, which an application may then write into generated configuration files.
