This project develops an SSH server and client widely used in wireless routers and compact distributions like OpenWrt. The new version addresses a vulnerability (CVE-2025-47203) in the SSH client implementation (dbclient program), which allows the execution of shell commands when processing specially formatted hostnames. The vulnerability arises from a lack of escaping of special characters in the hostname and the use of a command interpreter when executing commands in multihop mode (multiple hosts separated by commas). This vulnerability poses a risk to systems running dbclient with unverified hostnames.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63223\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0432\u044b\u043f\u0443\u0441\u043a \u043f\u0440\u043e\u0435\u043a\u0442\u0430 Dropbear 2025.88, \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u044e\u0449\u0435\u0433\u043e \u0441\u0435\u0440\u0432\u0435\u0440 \u0438 \u043a\u043b\u0438\u0435\u043d\u0442 SSH, \u043f\u043e\u043b\u0443\u0447\u0438\u0432\u0448\u0438\u0439 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0438\u0435 \u0432 \u0431\u0435\u0441\u043f\u0440\u043e\u0432\u043e\u0434\u043d\u044b\u0445 \u043c\u0430\u0440\u0448\u0440\u0443\u0442\u0438\u0437\u0430\u0442\u043e\u0440\u0430\u0445 \u0438 \u043a\u043e\u043c\u043f\u0430\u043a\u0442\u043d\u044b\u0445 \u0434\u0438\u0441\u0442\u0440\u0438\u0431\u0443\u0442\u0438\u0432\u0430\u0445, \u043f\u043e\u0434\u043e\u0431\u043d\u044b\u0445 OpenWrt. \u0412 \u043d\u043e\u0432\u043e\u0439 \u0432\u0435\u0440\u0441\u0438\u0438 \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0430 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c (CVE-2025-47203) \u0432 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 SSH-\u043a\u043b\u0438\u0435\u043d\u0442\u0430 (\u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u0430 dbclient), \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0430\u044f \u0432\u044b\u043f\u043e\u043b\u043d\u0438\u0442\u044c shell-\u043a\u043e\u043c\u0430\u043d\u0434\u044b \u043f\u0440\u0438 \u043e\u0431\u0440\u0430\u0431\u043e\u0442\u043a\u0435 \u0441\u043f\u0435\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u043e\u0444\u043e\u0440\u043c\u043b\u0435\u043d\u043d\u043e\u0433\u043e \u0438\u043c\u0435\u043d\u0438 \u0445\u043e\u0441\u0442\u0430. \u0423\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c \u0432\u044b\u0437\u0432\u0430\u043d\u0430 \u043e\u0442\u0441\u0443\u0442\u0441\u0442\u0432\u0438\u0435\u043c \u044d\u043a\u0440\u0430\u043d\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u0441\u043f\u0435\u0446\u0441\u0438\u043c\u0432\u043e\u043b\u043e\u0432 \u0432 \u0438\u043c\u0435\u043d\u0438 \u0445\u043e\u0441\u0442\u0430 \u0438 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u0435\u043c \u043a\u043e\u043c\u0430\u043d\u0434\u043d\u043e\u0433\u043e \u0438\u043d\u0442\u0435\u0440\u043f\u0440\u0435\u0442\u0430\u0442\u043e\u0440\u0430 \u043f\u0440\u0438 \u0437\u0430\u043f\u0443\u0441\u043a\u0435 \u043a\u043e\u043c\u0430\u043d\u0434 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-124640","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 -
