Permissions, Privileges, and Access Controls
Multiple unspecified vulnerabilities in Lyris ListManager 8.x before 8.95d, 9.2 before 9.2c, and 9.3 before 9.3b allow remote attackers to (1) gain list administrator privileges or (2) access arbitrary mailing lists via unknown vectors related to modification of client-side information; and (3) allow remote authenticated administrators to modify other account data by creating "new accounts that collide with existing accounts."
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
