This vulnerability arises from improper output encoding and lack of content security controls within the Droplets feature execution. \\n \\n #### Proof of Concept \\n \\n ## Prerequisites \\n – Valid administrator credentials \\n – Access to the LEPTON CMS administrative interface \\n \\n #### Exploitation Steps \\n \\n 1. Authentication \\n – Log into the LEPTON CMS administration panel with administrator privileges \\n \\n 2. Access Droplets Management \\n – Navigate to: Menu \\u003e Administration \\u003e Admin-Tools \\n – Select the \\”Droplets\\” option \\n \\n 3. Create Malicious Droplet \\n – Click \\”Create New\\” \\n – Enter a droplet name (e.g., xss-droplet) \\n – In the code field, insert the XSS payload: \\n \\n echo \\”\\u003cscript\\u003ealert(‘XSS!!’)\\u003c\/script\\u003e\\”; \\n \\n – Click \\”Save and Back\\” to store the droplet \\n \\n 4. Trigger Execution \\n – Edit or create any page within the CMS \\n – In the content editor, insert the droplet using the syntax: \\n [[xss-droplet]] \\n – Save the page modifications \\n \\n 5. Verify Exploitation \\n – Preview or visit the modified page \\n – The JavaScript alert box will be displayed, confirming successful XSS execution \\n – Any user visiting the affected page will execute the injected script”,”sourceHref”:”https:\/\/packetstorm.news\/download\/211036″,”cvss”:{“score”:0,”severity”:”NONE”,”vector”:”NONE”,”version”:”NONE”},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:”https:\/\/packetstorm.news\/files\/id\/211036\/”,”category_name”:”Exploit”,”post_link”:””,”product”:””,”version”:””,”vendor”:””,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
