CVE-2018-18326

71
FAUCET Score

CVE-2018-18326 affects DNN (DotNetNuke) versions 9.2 through 9.2.2, stemming from an incomplete fix for a prior vulnerability that leads to insufficient entropy in encryption key generation. This vulnerability carries a high CVSS score of 7.5, indicating a critical risk due to its network-exploitable nature, low attack complexity, and potential for high confidentiality impact. While not listed on CISA's KEV catalog, exploit code, including a Metasploit module for remote code execution via cookie deserialization, is publicly available. Despite this, there is minimal community discussion or media coverage surrounding this CVE.
