In Code42 app before 8.8.0, eval injection allows an attacker to change a device’s proxy configuration to use a malicious proxy auto-config (PAC) file, leading to arbitrary code execution. This affects Incydr Basic, Advanced, and Gov F1; CrashPlan Cloud; and CrashPlan for Small Business. (Incydr Professional and Enterprise are unaffected.)

Code42 environments with on-premises server versions 7.0.4 and earlier allow for possible remote code execution. When an administrator creates a local (non-SSO) user via a Code42-generated email, the administrator has the option to modify content for the email invitation. If the administrator entered template language code in the subject line, that code could be interpreted by the email generation services, potentially resulting in server-side code injection.

Code42 server through 7.0.2 for Windows has an Untrusted Search Path. In certain situations, a non-administrative attacker on the local server could create or modify a dynamic-link library (DLL). The Code42 service could then load it at runtime, and potentially execute arbitrary code at an elevated privilege on the local server.

In Code42 Enterprise 6.7.5 and earlier, 6.8.4 through 6.8.8, and 7.0.0 a vulnerability has been identified that may allow arbitrary files to be uploaded to Code42 servers and executed. This vulnerability could allow an attacker to create directories and save files on Code42 servers, which could potentially lead to code execution.

In Code42 for Enterprise through 6.8.4, an administrator without web restore permission but with the ability to manage users in an organization can impersonate a user with web restore permission. When requesting the token to do a web restore, an administrator with permission to manage a user could request the token of that user. If the administrator was not authorized to perform web restores but the user was authorized to perform web restores, this would allow the administrator to impersonate the user with greater permissions. In order to exploit this vulnerability, the user would have to be an administrator with access to manage an organization with a user with greater permissions than themselves.

The Code42 app before 6.8.4, as used in Code42 for Enterprise, on Linux installs with overly permissive permissions on the /usr/local/crashplan/log directory. This allows a user to manipulate symbolic links to escalate privileges, or show the contents of sensitive files that a regular user would not have access to.
