Prior to versions 20.7-cert9, 20.18.2, 21.12.1, 22.8.2, and 23.2.2, the asterisk\/contrib\/scripts\/ast_coredumper runs as root, as noted by the NOTES tag on line 689 of the ast_coredumper file. The script will source the contents of \/etc\/asterisk\/ast_debug_tools.conf, which resides in a folder that is writeable by the asterisk user:group. Due to the \/etc\/asterisk\/ast_debug_tools.conf file following bash semantics and it being loaded; an attacker with write permissions may add or modify the file such that when the root ast_coredumper is run; it would source and thereby execute arbitrary bash code found in the \/etc\/asterisk\/ast_debug_tools.conf. This issue has been patched in versions 20.7-cert9, 20.18.2, 21.12.1, 22.8.2, and 23.2.2.<\/p>\n<p>Severity: 0.0 | NA<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2026-23741 Published : Feb. 6, 2026, 4:47 p.m. | 31\u00a0minutes ago Description : Asterisk is an open source private branch exchange and telephony toolkit.
