DescriptionCVE.org

A vulnerability in the web-based management interface of Cisco Catalyst SD-WAN Manager could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system.

This vulnerability is due to insufficient access control enforcement for specific template types that are not included in the encryption allowlist. A low-privileged attacker could exploit this vulnerability by viewing logs on the local system or on a remote logging server. A successful exploit could allow the attacker to view sensitive authentication credentials, which could lead to further compromise of network infrastructure and connected services.

AnalysisAI

Cleartext credential exposure in Cisco Catalyst SD-WAN Manager's web-based management interface allows an authenticated low-privileged remote attacker to read sensitive authentication material from system logs. The root cause is an incomplete encryption allowlist: specific template types are excluded from the encryption policy, resulting in sensitive values being written to logs in cleartext - accessible both on the local system and on any configured remote logging server. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid low-privileged authenticated account on the Cisco Catalyst SD-WAN Manager web-based management interface - PR:L per the CVSS vector confirms authentication is mandatory. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) accurately reflects a low-barrier, network-accessible information disclosure requiring only a low-privileged authenticated account - a realistic scenario in enterprise environments where multiple operators share the management plane with varying privilege levels. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Consult the Cisco Security Advisory at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-infodis-SPuJBDCe for specific fixed-version guidance - the input data does not include an explicit patched release identifier, so citing a version here would be speculative. … Detailed patch versions, workarounds, and compensating controls in full report.
