Acer vulnerabilities and threats

The FieldX MDM adb messaging topic passes unverified payloads directly into Runtime.exec(), allowing command/instruction injection.

The upload.cgi binary, responsible for processing device backups, contains a hardcoded AES encryption key. This allows an attacker to decrypt, modify, and re-encrypt system backups, facilitating persistent backdoor injection.

The acer_cgi.log file in the device firmware is accessible without authentication via the web interface. This file contains cleartext login credentials (for web and Telnet), leading to unauthorized system access.

Crafted MQTT messages can trigger command injection, resulting in root-level code execution on the target device.

Improper access control in the MQTT broker allows wildcard topic subscriptions, exposing all MQTT traffic to unauthorized actors.

Web endpoints intended for the Acer Connect app improperly validate the HTTP Authorization header, failing to block requests when Base64 decoding fails.

The Wi-Fi device blocking feature fails to sanitize MAC address input, allowing injection and execution of arbitrary shell commands.

Unauthenticated Debug Service. The /sbin/mtk_dut binary is exposed on TCP port 9000 without authentication, allowing any LAN-based attacker to execute arbitrary UCC commands.

A Local Privilege Escalation (LPE) vulnerability affects Acer NitroSense software versions prior to 3.01.3052. The vulnerability stems from the the PSAdminAgent service, which creates a Named Pipe with a weak Access Control List (ACL). This allows any authenticated local user to connect and send commands. Because the service does not check the caller's privileges before running file deletion commands, a low-privileged local user can exploit this to delete arbitrary files with system authority.

CVE-2026-9490 is a medium severity vulnerability in Acer Care Center version 4.0 where the ACCSvc service creates a Named Pipe with a weak security descriptor. This flaw allows an authenticated local user to send a crafted message to the pipe, causing the service to crash with exit code 1067 (ERROR_PROCESS_ABORTED). The vulnerability results in local denial of service by disrupting the service operation. Acer advises updating to the latest version to mitigate this issue, but no specific patch or official fix details are currently confirmed.

Acer NitroSense V3 versions before 3.01.3052 contain a local privilege escalation vulnerability due to improper configuration of a Windows Named Pipe. This flaw allows any authenticated local user to execute arbitrary code and delete files with SYSTEM privileges by exploiting a custom protocol exposed by the Named Pipe. The vulnerability is classified as a path traversal and improper access control issue, leading to high-severity impact on affected systems.

PredatorSense version 3.00.3136 to 3.00.3196 contain Local Privilege Escalation (LPE) vulnerability.The program exposes a Windows Named Pipe that uses a custom protocol to invoke internal functions. However, this Named Pipe is misconfigured, allowing any authenticated local user to execute arbitrary code with NT AUTHORITY\SYSTEM privileges and to delete arbitrary files with SYSTEM privileges. By leveraging this, an attacker can execute arbitrary code on the target system with elevated privileges.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in artplacer ArtPlacer Widget artplacer-widget allows Stored XSS.This issue affects ArtPlacer Widget: from n/a through <= 2.23.2.

ListCheck.exe developed by Acer has a Local Privilege Escalation vulnerability. Authenticated local attackers can replace ListCheck.exe with a malicious executable of the same name, which will be executed by the system and result in privilege escalation.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in artplacer ArtPlacer Widget artplacer-widget allows Blind SQL Injection.This issue affects ArtPlacer Widget: from n/a through <= 2.22.9.2.

Markdownify is a Model Context Protocol server for converting almost anything to Markdown. Versions below 0.0.2 contain a command injection vulnerability, caused by the unsanitized use of input parameters within a call to child_process.exec, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, >, &&, etc.). This issue is fixed in version 0.0.2.

Acer ControlCenter contains Remote Code Execution vulnerability. The program exposes a Windows Named Pipe that uses a custom protocol to invoke internal functions. However, this Named Pipe is misconfigured, allowing remote users with low privileges to interact with it and access its features. One such feature enables the execution of arbitrary programs as NT AUTHORITY/SYSTEM. By leveraging this, remote attackers can execute arbitrary code on the target system with elevated privileges.

A vulnerability exists in UEFI implementations that use a hard-coded software-based Platform Key (PK). An attacker in possession of the corresponding PK private key can sign arbitrary UEFI executables or firmware components, causing them to be trusted by affected systems and potentially bypassing UEFI Secure Boot trust validation.
