CVE-2019-12889

CVE-2019-12889

An unauthenticated privilege escalation exists in SailPoint Desktop Password Reset 7.2. A user with local access to only the Windows logon screen can escalate their privileges to NT AUTHORITYSystem. An attacker would need local access to the machine for a successful exploit. The attacker must disconnect the computer from the local network / WAN and connect it to an internet facing access point / network. At that point, the attacker can execute the password-reset functionality, which will expose a web browser. Browsing to a site that calls local Windows system functions (e.g., file upload) will expose the local file system. From there an attacker can launch a privileged command shell.

CVE-2019-15239

CVE-2019-15239

In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139.

CVE-2019-15231

CVE-2019-15231

Webmin 1.890, in a default installation, contains a backdoor that allows an unauthenticated attacker to remotely execute commands. This is different from CVE-2019-15107. NOTE: as of 2019-08-19, the vendor reports that "at some point" malicious code was inserted into their build infrastructure, but was not inserted into any GitHub repository.
