CVE-2025-46883 in Experience Manager
Summary
by MITRE • 06/11/2025
Adobe Experience Manager versions 6.5.22 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.

Adobe Experience Manager represents a comprehensive digital experience platform that serves as a cornerstone for enterprise content management and digital asset handling. This platform processes user inputs through various form fields and content management interfaces, making it a prime target for attackers seeking to exploit input validation weaknesses. The vulnerability under discussion affects versions 6.5.22 and earlier, indicating that this represents a long-standing issue that has persisted across multiple releases of the platform. Organizations relying on these older versions face significant exposure given the widespread adoption of Adobe Experience Manager in enterprise environments. The platform's architecture includes numerous interfaces where users can submit content, making it essential to understand how input validation failures can compromise entire systems. Security researchers have identified that the vulnerability exists within the form processing mechanisms of the platform, specifically where user-supplied data is not properly sanitized before being rendered back to users.
The technical flaw manifests as a stored cross-site scripting vulnerability that occurs when user input is not adequately validated or sanitized before being stored and subsequently displayed. This particular weakness allows attackers to inject malicious JavaScript code into form fields that are later rendered in web pages. The vulnerability operates at the application layer where user-supplied data flows through multiple processing steps before reaching the final output stage. The stored nature of the vulnerability means that the malicious script is persisted in the system's database or storage mechanism, making it available for execution whenever users access the affected pages. The attack vector exploits the platform's failure to implement proper input sanitization routines that would normally strip or encode dangerous characters in user-provided content. This flaw specifically targets the rendering pipeline where form data is processed for display, creating a persistent execution environment for malicious code. The vulnerability aligns with CWE-79 which classifies improper neutralization of input during web page generation as a critical weakness. Attackers can leverage this vulnerability by crafting malicious payloads that contain JavaScript code within form fields, knowing that these payloads will execute in the context of other users' browsers when they view the affected content.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with a foothold for more sophisticated attacks within the target environment. A low privileged attacker can potentially escalate their access by using the stored XSS to steal session cookies, redirect users to malicious sites, or perform actions on behalf of authenticated users. The vulnerability enables attackers to compromise user sessions and potentially gain unauthorized access to sensitive content management systems. When executed, the malicious JavaScript can harvest user credentials, monitor user activities, or redirect users to phishing sites that appear legitimate within the context of the Adobe Experience Manager interface. The persistent nature of stored XSS makes it particularly dangerous as the attack can affect multiple users over extended periods. Organizations may experience data breaches, unauthorized content modifications, or complete compromise of user sessions depending on how attackers leverage the vulnerability. The impact is compounded when considering that Adobe Experience Manager often handles sensitive corporate data, making successful exploitation particularly damaging to enterprise security postures. This vulnerability can also facilitate further attacks such as privilege escalation or lateral movement within the network if attackers can use the stored XSS to access administrative functions.
Mitigation strategies for this vulnerability should focus on immediate remediation through software updates to versions that address the stored XSS flaw. Organizations must implement comprehensive input validation and sanitization procedures that encode or filter dangerous characters before storing user-supplied content. The implementation of Content Security Policy headers can provide additional protection against script execution in vulnerable contexts. Security teams should conduct thorough audits of all form fields and input mechanisms within Adobe Experience Manager installations to identify and remediate similar weaknesses. Regular security assessments and penetration testing should include validation of input handling routines to prevent similar vulnerabilities from emerging. Organizations should also consider implementing web application firewalls that can detect and block known XSS attack patterns. The principle of least privilege should be enforced to minimize the impact of potential exploitation, ensuring that users have only the permissions necessary for their roles. Incident response procedures should be updated to include detection and response protocols for stored XSS attacks within content management systems. Organizations should also implement monitoring solutions that can detect unusual patterns in user input or content modifications that might indicate exploitation attempts. Regular security training for content managers and administrators can help prevent accidental exploitation through social engineering or insider threats. The remediation process should include comprehensive testing to ensure that the applied fixes do not break existing functionality while providing adequate protection against the identified vulnerability.
