### [CVE-2017-12424](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-12424) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brighgreen) ### Description In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts. ### POC #### Reference No PoCs from references. #### Github - https://github.com/flyrev/security-scan-ci-presentation - https://github.com/yfoelling/yair
