Security readout for executives and security teams
Plain-English summary
RSA Authentication Manager before 8.4 P10 could let a highly privileged Security Console administrator plant script content in a report page. The script may run when another Security Console administrator views that page. This is mainly an administrative-console integrity and confidentiality risk, not a broad unauthenticated internet exploit.
Executive priority
Treat this as a moderate-priority identity infrastructure issue. It requires privileged access, but it affects an authentication management console where administrator trust and session integrity matter.
Technical view
This is a stored cross-site scripting issue in the RSA Authentication Manager Security Console. CVSS 3.0 is 4.8: network reachable, low attack complexity, high privileges required, user interaction required, scope changed, low confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is limited to organizations running RSA Authentication Manager versions before 8.4 P10, with Security Console access available to administrators. The source bundle does not provide specific CPEs or deployment patterns.
Exploitation context
The source states exploitation requires a malicious Security Console administrator with advanced privileges and another administrator viewing the affected report page. KEV is false, and no cited source states active exploitation.
Researcher notes
The key constraints are high required privileges and administrator user interaction. The available sources identify the vulnerable component and fixed version threshold but do not document public exploitation, detailed affected build ranges, or exploit mechanics.
Mitigation direction
- Upgrade affected RSA Authentication Manager deployments to 8.4 P10 or later per vendor guidance.
- Review RSA's advisory before applying changes or choosing compensating controls.
- Restrict Security Console administrator privileges to trusted, necessary personnel only.
- Monitor administrative report changes and console activity for unexpected HTML or script-like content.
Validation and detection
- Inventory RSA Authentication Manager instances and confirm exact version and patch level.
- Check whether any deployment is earlier than 8.4 P10.
- Review Security Console administrator accounts for excessive or unnecessary advanced privileges.
- Inspect relevant administrative report pages for unexpected stored content.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
