CVE-2021-43271


Riverbed AppResponse 11.8.0, 11.8.5, 11.8.5a, 11.9.0, 11.9.0a, 11.10.0, 11.11.0, 11.11.0a, 11.11.1, 11.11.1a, 11.11.5, and 11.11.5a (when configured to use local, RADIUS, or TACACS authentication) logs usernames and passwords if either is entered incorrectly. If a user enters an incorrect username and/or password when logging into the WebUI, these attempted credentials are included in an error message that is logged in the WebUI log file. A log entry does not appear if the username and password provided correctly match a valid set of credentials. This also does not happen if AppResponse is configured to use SAML authentication. The WebUI log file is included in subsequent diagnostic system dumps that are generated. (Only users with Full Control access to the System Configuration permission can generate system dumps. By default, only System Administrators have Full Control access to the System Configuration permission.)


Security Impact Summary

This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.8, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from riverbed organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2022, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For riverbed's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
