Affected is an unknown function of the file \/squashfs-root\/etc\/shadow of the component Web Interface. The manipulation leads to use of hard-coded password. The attack must be carried out locally. The attack&#8217;s complexity is rated as high. The exploitability is told to be difficult. The exploit is publicly available and might be used. Upgrading to version 2.3.13 is able to address this issue. It is recommended to upgrade the affected component. The vendor explains: \\&#8221;[T]he firmware does store a default password of &#8216;admin&#8217;. This password has been deprecated since LT500E firmware version 2.3.13 and is no longer used. The LT500E does not have an administrator password set by default; a new password (at least 8 characters ) must be manually created upon first login the web management page.\\&#8221;&#8221;,&#8221;published&#8221;:&#8221;2025-08-31T10:02:06.702Z&#8221;,&#8221;modified&#8221;:&#8221;2025-08-31T10:02:06.702Z&#8221;,&#8221;type&#8221;:&#8221;cve&#8221;,&#8221;title&#8221;:&#8221;Cudy LT500E Web shadow hard-coded password&#8221;,&#8221;source&#8221;:&#8221;VulDB&#8221;,&#8221;references&#8221;:&#8221;https:\/\/vuldb.com\/?id.322014\\nhttps:\/\/vuldb.com\/?ctiid.322014\\nhttps:\/\/vuldb.com\/?submit.639346\\nhttps:\/\/github.com\/XXRicardo\/iot-cve\/blob\/main\/CUDY\/LT500E-R42-2.3.13.md\\nhttps:\/\/github.com\/XXRicardo\/iot-cve\/blob\/main\/CUDY\/LT500E-R42-2.3.13.md#steps-to-reproduce&#8221;,&#8221;id&#8221;:&#8221;CVE-2025-9725&#8243;,&#8221;bulletinFamily&#8221;:&#8221;&#8221;,&#8221;cwe&#8221;:[&#8220;CWE-259&#8243;,&#8221;CWE-255&#8243;],&#8221;cvelist&#8221;:null,&#8221;sourceData&#8221;:&#8221;Cudy LT500E 2.3.0\\nCudy LT500E 2.3.1\\nCudy LT500E 2.3.2\\nCudy LT500E 2.3.3\\nCudy LT500E 2.3.4\\nCudy LT500E 2.3.5\\nCudy LT500E 2.3.6\\nCudy LT500E 2.3.7\\nCudy LT500E 2.3.8\\nCudy LT500E 2.3.9\\nCudy LT500E 2.3.10\\nCudy LT500E 2.3.11\\nCudy LT500E 2.3.12&#8243;,&#8221;sourceHref&#8221;:&#8221;&#8221;,&#8221;cvss&#8221;:{&#8220;score&#8221;:2,&#8221;severity&#8221;:&#8221;LOW&#8221;,&#8221;vector&#8221;:&#8221;CVSS:4.0\/AV:L\/AC:H\/AT:N\/PR:L\/UI:N\/VC:L\/VI:N\/VA:N\/SC:N\/SI:N\/SA:N\/E:P&#8221;,&#8221;version&#8221;:&#8221;4.0&#8243;},&#8221;cvss2&#8243;:{},&#8221;cvss3&#8243;:{&#8220;version&#8221;:&#8221;&#8221;,&#8221;vectorString&#8221;:&#8221;&#8221;,&#8221;baseScore&#8221;:0,&#8221;baseSeverity&#8221;:&#8221;&#8221;,&#8221;attackVector&#8221;:&#8221;&#8221;,&#8221;attackComplexity&#8221;:&#8221;&#8221;,&#8221;privilegesRequired&#8221;:&#8221;&#8221;,&#8221;userInteraction&#8221;:&#8221;&#8221;,&#8221;scope&#8221;:&#8221;&#8221;,&#8221;confidentialityImpact&#8221;:&#8221;&#8221;,&#8221;integrityImpact&#8221;:&#8221;&#8221;,&#8221;availabilityImpact&#8221;:&#8221;&#8221;,&#8221;cvssV3&#8243;:{&#8220;version&#8221;:&#8221;&#8221;,&#8221;vectorString&#8221;:&#8221;&#8221;,&#8221;baseScore&#8221;:0,&#8221;baseSeverity&#8221;:&#8221;&#8221;,&#8221;attackVector&#8221;:&#8221;&#8221;,&#8221;attackComplexity&#8221;:&#8221;&#8221;,&#8221;privilegesRequired&#8221;:&#8221;&#8221;,&#8221;userInteraction&#8221;:&#8221;&#8221;,&#8221;scope&#8221;:&#8221;&#8221;,&#8221;confidentialityImpact&#8221;:&#8221;&#8221;,&#8221;integrityImpact&#8221;:&#8221;&#8221;,&#8221;availabilityImpact&#8221;:&#8221;&#8221;}},&#8221;href&#8221;:&#8221;&#8221;,&#8221;category_name&#8221;:&#8221;CVE&#8221;,&#8221;post_link&#8221;:&#8221;&#8221;,&#8221;product&#8221;:&#8221;LT500E&#8221;,&#8221;version&#8221;:&#8221;2.3.0&#8243;,&#8221;vendor&#8221;:&#8221;Cudy&#8221;,&#8221;ai_description&#8221;:&#8221;&#8221;,&#8221;ai_severity&#8221;:&#8221;&#8221;,&#8221;ai_vendor&#8221;:&#8221;&#8221;,&#8221;ai_product&#8221;:&#8221;&#8221;,&#8221;ai_version&#8221;:&#8221;&#8221;,&#8221;ai_score&#8221;:0}<\/p>\n","protected":false},"excerpt":{"rendered":"<p>{&#8220;lastseen&#8221;:&#8221;&#8221;,&#8221;description&#8221;:&#8221;A vulnerability was identified in Cudy LT500E up to 2.3.12.
