DotNetNuke (DNN) Inadequate Encryption Strength Vulnerability

DotNetNuke (DNN) contains an inadequate encryption strength vulnerability resulting from the use of a weak encryption algorithm to protect input parameters.

Added to KEV: 2021-11-03Federal patch deadline: 2022-05-03

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This inadequate encryption strength vulnerability in DotNetNuke (DNN) results from the use of a weak encryption algorithm to protect input parameters. This weakness could allow attackers to decrypt sensitive information or manipulate parameters. The high EPSS score of 0.91142 indicates a very high likelihood of exploitation, making this a critical vulnerability. Its presence in CISA's KEV catalog confirms it has been actively exploited.

This vulnerability is actively exploited in the wild. While the exact vector is not specified, weak encryption often facilitates remote attacks.

Recommended Action

Apply the latest security patches or upgrades for DotNetNuke (DNN) to address this encryption weakness. Ensure that strong, modern encryption algorithms are used for all sensitive data and communications.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2018-15811 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2018-15811 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
