This command will be executed by the vulnerable application.&#8221;<br \/>\nwatchTowr researchers Sina Kheirkhah and Piotr Bazydlo, CODE WHITE GmbH&#8217;s Markus Wulftange, and VulnCheck&#8217;s Cale Black have been credited with discovering and reporting the vulnerability.<br \/>\nThe security hole has been addressed in version Build 9511, released on January 15, 2026. The same build also patches another critical flaw (CVE-2026-23760, CVSS score: 9.3) that has since come under active exploitation in the wild.<\/p>\n<p>In addition, SmarterTools has shipped fixes to plug a medium-severity security vulnerability (CVE-2026-25067, CVSS score: 6.9) that could allow an attacker to facilitate NTLM relay attacks and unauthorized network authentication.<br \/>\nIt has been described as a case of unauthenticated path coercion affecting the background-of-the-day preview endpoint.<br \/>\n&#8220;The application base64-decodes attacker-supplied input and uses it as a filesystem path without validation,&#8221; VulnCheck noted in an alert.<br \/>\n&#8220;On Windows systems, this allows UNC [Universal Naming Convention] paths to be resolved, causing the SmarterMail service to initiate outbound SMB authentication attempts to attacker-controlled hosts. This can be abused for credential coercion, NTLM relay attacks, and unauthorized network authentication.&#8221;<br \/>\nThe vulnerability has been patched in Build 9518, released on January 22, 2026. With two vulnerabilities in SmarterMail coming under active exploitation over the past week, it&#8217;s essential that users update to the latest version as soon as possible.<\/p>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SmarterMail Fixes Critical Unauthenticated RCE Flaw with CVSS 9.3 Score https:\/\/thehackernews.com\/2026\/01\/smartermail-fixes-critical.html Publish Date: 2026-01-30 02:09:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":182958,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEg68yf4tK-m7j1I6zRCo-SBeQ4cCXmLiwvPRMoEXS_I8m7V53UUmULEbWr2vVAEJd34U0hknt8J5wnzcNv1kGayBLApw6mu0UmRZRyCstoXJAteTDrnRZBnoh5n3ROzBarjsRgPXeV_1WDsxQmg5ysAETrtYI3L9oNWnX246xTksVuWWqi34CzJCJnFc0uv\/s1700-e365\/smartertools.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[27],"class_list":["post-182957","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/182957"}],"collection":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=182957"}],"version-history":[{"count":1,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/182957\/revisions"}],"predecessor-version":[{"id":182959,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/182957\/revisions\/182959"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/182958"}],"wp:attachment":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=182957"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=182957"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=182957"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
