Title
Local Privilege Escalation in servereye client (sensorhub)
Summary
The servereye client (also known as sensorhub, technically ClientAgentContainerService) versions 20.15 and earlier are vulnerable to Local Privilege Escalation. The high-privileged service SE3Recovery (EmergencyRecoveryService.exe), running as SYSTEM, periodically monitors the directory %ProgramData%\ServerEye3\update\ for a trigger file named "update_available". Due to insufficient access restrictions on this directory, a local standard user can create the trigger file and provide a path to a directory containing malicious JSON instructions. The service subsequently executes the utility UpdaterAction.exe with SYSTEM privileges, which parses the instructions and performs an unvalidated file copy from a user-controlled source to a protected system destination (e.g., overwriting a service binary). This leads to full system compromise as the service automatically restarts the overwritten binary with SYSTEM privileges.

Title
HP Easy Start for macOS: CVE-2026-12554 / CVE-2026-12555 / CVE-2026-12556
Summary
Hello Full Disclosure list,
Cipher Security Labs has published technical details for three
High-severity vulnerabilities affecting HP Easy Start for macOS. The
issues were coordinated with HP and are addressed in HP Easy Start
2.16.7.260722 and later under HPSBPI04124.
Research title:
Rooted in Trust: Breaking HP Easy Start’s macOS Privilege Boundaries
Affected product:
HP Easy Start for macOS
Affected versions:
Versions prior to 2.16.7.260722
Validated vulnerable sample:
2.16.0 (build 251010)
Fixed:
2.16.7.260722 and later
CVE-2026-12554
CVSS 4.0: 8.5 High
CWE-1104: Use of Unmaintained Third-Party Components
The affected software-download path contained an OSPFTP stack wired
into component acquisition, including fallback URL-scheme handling.
The research does not claim that every installation uses FTP on the
normal path; the finding is that an unmaintained FTP-capable component
remained active on the privileged software-delivery surface.
CVE-2026-12555
CVSS 4.0: 7.7 High
CWE-379: Creation of Temporary File in Directory with Insecure Permissions
The HP Uninstaller used predictable paths under /tmp and /private/tmp
while operating with administrative privileges. An unprivileged local
user could prepare a symbolic link before the elevated process opened
the path. In our PoC, after the user approved the normal macOS
administrative prompt, HP-generated log data was appended through the
symlink to an attacker-selected proof file as root.
We intentionally describe this as privileged file
modification/corruption rather than unrestricted arbitrary file write:
destination control is demonstrated, but the log content itself is
generated by HP Easy Start. Follow-on privilege escalation would
require a suitable environment-specific target and is not automatic.
CVE-2026-12556
CVSS 4.0: 7.7 High
CWE-319: Cleartext Transmission of Sensitive Information
HP Easy Start 2.16.0 set NSAllowsArbitraryLoads=true in its App
Transport Security policy and retained cleartext FTP as a
software-download fallback. Together these conditions expanded the
circumstances in which a network-positioned attacker could interfere
with software-component acquisition when the primary scheme failed.
The research does not claim that NSAllowsArbitraryLoads alone disables
certificate validation, that every install falls back to FTP, or that
package substitution automatically yields code execution. Those are
separate conditions and are treated separately in the analysis.
Related design note — not a fourth CVE
The 2.16.0 build also contained SWHelper, a privileged helper using
Apple’s deprecated AuthorizationExecuteWithPrivileges API. The legacy
API and path-oriented privileged install flow were confirmed, but an
end-to-end package-swap TOCTOU against the production staging path was
not demonstrated. This is therefore documented only as a risky
privilege-boundary design with conditional exploitability.
Remediation validation
In 2.16.7 (build 260722), Cipher Security Labs validated that:
• the vulnerable Uninstaller bundle was removed from the package tested;
• OSPFTP download classes and FTP software-download markers were absent;
• blanket ATS relaxation was tightened;
• SWHelper and AuthorizationExecuteWithPrivileges were removed;
• a new privileged helper used SMAppService and NSXPCConnection;
• the helper restricted clients by code-signing identity; and
• package SHA-256 was verified using an already-open file descriptor
before invoking /usr/sbin/installer.

Title
Insecure handling of file paths allows multiple local attacks
Summary
Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths.
This issue affects Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.

Mitigation
Requirements
Many contemporary languages have functions which properly handle this condition. Older C temp file functions are especially susceptible.
Mitigation
Implementation
Try to store sensitive tempfiles in a directory which is not world readable -- i.e., per-user directories.
Mitigation
Implementation
Avoid using vulnerable temp file functions.
