CVE-2024-57520

Name	CVE-2024-57520
Description	Insecure Permissions vulnerability in asterisk v22 allows a remote attacker to execute arbitrary code via the action_createconfig function.

Source	CVE (at NVD; CERT, ENISA, LWN, oss-sec, fulldisc, Debian ELTS, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
