CVE-2010-1168 – Safe: Intended restriction bypass via object references

https://notcve.org/view.php?id=CVE-2010-1168

The Safe (aka Safe.pm) module before 2.25 for Perl allows context-dependent attackers to bypass intended (1) Safe::reval and (2) Safe::rdo access restrictions, and inject and execute arbitrary code, via vectors involving implicitly called methods and implicitly blessed objects, as demonstrated by the (a) DESTROY and (b) AUTOLOAD methods, related to "automagic methods." El módulo Safe (Safe.pm) en versiones anteriores a la v2.25 de Perl permite a atacantes, dependiendo del contexto, evitar las restricciones de acceso previstas (1) Safe::reval y (2) Safe::rdo, e inyectar y ejecutar código de su elección, a través de vectores de ataque que involucran métodos llamados implícitamente y objetos implícitamente "blessed", como se ha demostrado por los métodos (a) DESTROY y (b) AUTOLOAD. Relacionado con los "automagic methods". • http://blogs.perl.org/users/rafael_garcia-suarez/2010/03/new-safepm-fixes-security-hole.html http://blogs.sun.com/security/entry/cve_2010_1168_vulnerability_in http://cpansearch.perl.org/src/RGARCIA/Safe-2.27/Changes http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10735 http://secunia.com/advisories/40049 http://secunia.com/advisories/40052 http://secunia.com/advisories/42402 http://securitytracker.com/id? • CWE-264: Permissions, Privileges, and Access Controls •
