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 that runs in another administrator's browser during a specific domain-mapping action. This is not a broad remote compromise, but it can affect an identity security administration console and should be remediated where exposed.
Executive priority
Prioritize remediation for identity infrastructure, but treat this as moderate urgency because exploitation requires existing advanced administrator access and a second administrator interaction.
Technical view
CVE-2020-5340 is a stored XSS issue in the RSA Authentication Manager Security Console. Exploitation requires an authenticated Security Console administrator with advanced privileges and user interaction by another administrator. The CVSS 3.0 score is 4.8, with low confidentiality and integrity impact and no availability impact.
Likely exposure
Exposure is limited to deployments running RSA Authentication Manager versions earlier than 8.4 P10, especially where multiple advanced Security Console administrators manage security domain mappings.
Exploitation context
The provided sources do not indicate active exploitation, and the CVE is not marked as KEV. The attack requires high privileges first, then execution in another administrator's browser when they attempt to change the default security domain mapping.
Researcher notes
Key constraints are high required privileges, stored XSS behavior, and a narrow trigger path involving default security domain mapping. The source bundle does not provide proof-of-concept details, exploit prevalence, or broader affected product claims.
Mitigation direction
- Upgrade RSA Authentication Manager to 8.4 P10 or later where applicable.
- Review RSA vendor advisory DOC-111092 for supported remediation guidance.
- Restrict advanced Security Console administrator privileges to required personnel only.
- Review administrative content fields for unexpected HTML or JavaScript.
Validation and detection
- Inventory RSA Authentication Manager deployments and confirm exact versions.
- Identify any instances running versions earlier than 8.4 P10.
- Review Security Console administrator roles for excessive advanced privileges.
- Check administrative audit records for unexpected Security Console changes.
