Brother SAPSprint 7.60 contains an unquoted service path vulnerability in the SAPSprint service binary that allows local attackers to escalate privileges. Attackers can place a malicious executable in the Program Files directory path to be executed with LocalSystem privileges when the service starts automatically.

Brother BRAdmin Professional 3.75 contains an unquoted service path vulnerability in the BRAScheduler service that allows local users to potentially execute arbitrary code. Attackers can place a malicious executable named 'BRAdmin' in the C:\Program Files (x86)\Brother\ directory to gain local system privileges.

Brother BRAgent 1.38 contains an unquoted service path vulnerability in the WBAAgentClient service running with LocalSystem privileges. Attackers can exploit the unquoted path in C:\Program Files (x86)\Brother\BRAgent\ to inject and execute malicious code with elevated system permissions.

Brother BRPrint Auditor 3.0.7 contains an unquoted service path vulnerability in its Windows service configurations that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted file paths in BrAuSvc and BRPAAgent services to inject malicious executables and escalate privileges on the system.

Android App "Brother iPrint&Scan" versions 6.13.7 and earlier improperly uses an external cache directory. If exploited, application-specific files may be accessed from other malicious applications.

By using the "uscan" protocol provided by the eSCL specification, an attacker can discover the serial number of multi-function printers that implement the Brother-provided firmware. This serial number can, in turn, can be leveraged by the flaw described by CVE-2024-51978 to calculate the default administrator password. This flaw is similar to CVE-2024-51977, with the only difference being the protocol by which an attacker can use to learn the remote device's serial number. The eSCL/uscan vector is typically only exposed on the local network. Any discovery service that implements the eSCL specification can be used to exploit this vulnerability, and one such implementation is the runZero Explorer. Changing the default administrator password will render this vulnerability virtually worthless, since the calculated default administrator password would no longer be the correct password.

An unauthenticated attacker who can connect to TCP port 9100 can issue a Printer Job Language (PJL) command that will crash the target device. The device will reboot, after which the attacker can reissue the command to repeatedly crash the device. A malformed PJL variable FORMLINES is set to a non number value causing the target to crash.

An unauthenticated attacker may perform a limited server side request forgery (SSRF), forcing the target device to open a TCP connection to an arbitrary port number on an arbitrary IP address. This SSRF leverages the WS-Addressing ReplyTo element in a Web service (HTTP TCP port 80) SOAP request. The attacker can not control the data sent in the SSRF connection, nor can the attacker receive any data back. This SSRF is suitable for TCP port scanning of an internal network when the Web service (HTTP TCP port 80) is exposed across a network segment.

An unauthenticated attacker who knows the target device's serial number, can generate the default administrator password for the device. An unauthenticated attacker can first discover the target device's serial number via CVE-2024-51977 over HTTP/HTTPS/IPP, or via a PJL request, or via an SNMP request.

An issue was discovered on Brother MFC-J491DW C1806180757 devices. The printer's web-interface password hash can be retrieved without authentication, because the response header of any failed login attempt returns an incomplete authorization cookie. The value of the authorization cookie is the MD5 hash of the password in hexadecimal. An attacker can easily derive the true MD5 hash from this, and use offline cracking attacks to obtain administrative access to the device.

Improper link resolution before file access ('Link Following') issue exists in iPrint&Scan Desktop for Windows versions 11.0.0 and earlier. A symlink attack by a malicious user may cause a Denial-of-service (DoS) condition on the PC.

Null pointer dereference vulnerability exists in multiple vendors MFPs and printers which implement Debut web server 1.2 or 1.3. Processing a specially crafted request may lead an affected product to a denial-of-service (DoS) condition. As for the affected products/models/versions, see the detailed information provided by each vendor.

Brother iPrint&Scan V6.11.2 and earlier contains an improper access control vulnerability. This vulnerability may be exploited by the other app installed on the victim user's Android device, which may lead to displaying the settings and/or log information of the affected app as a print preview.

Some Brother printers (such as the HL-L8360CDW v1.20) were affected by a heap buffer overflow vulnerability as the IPP service did not parse attribute names properly. This would allow an attacker to execute arbitrary code on the device.

Some Brother printers (such as the HL-L8360CDW v1.20) were affected by a stack buffer overflow vulnerability as the web server did not parse the cookie value properly. This would allow an attacker to execute arbitrary code on the device.

Some Brother printers (such as the HL-L8360CDW v1.20) were affected by different information disclosure vulnerabilities that provided sensitive information to an unauthenticated user who visits a specific URL.

Brother MFC-9970CDW 1.10 devices with Firmware L contain a Frameable response (Clickjacking) vulnerability which could allow remote attackers to obtain sensitive information.

Brother MFC-9970CDW 1.10 firmware L devices contain an information disclosure vulnerability which allows remote attackers to view private IP addresses and other sensitive information.

Brother MFC-9970CDW 1.10 firmware L devices contain an information disclosure vulnerability which allows remote attackers to view sensitive information from referrer logs due to inadequate handling of HTTP referrer headers.

Brother MFC-9970CDW 1.10 firmware L devices contain a security bypass vulnerability which allows physically proximate attackers to gain unauthorized access.

Brother MFC-9970CDW devices with firmware 0D allow cleartext submission of passwords.

Cross-site scripting (XSS) vulnerability on Brother HL series printers allows remote attackers to inject arbitrary web script or HTML via the url parameter to etc/loginerror.html.

The Debut embedded http server contains a remotely exploitable denial of service where a single malformed HTTP POST request can cause the server to hang until eventually replying (~300 seconds) with an HTTP 500 error. While the server is hung, print jobs over the network are blocked and the web interface is inaccessible. An attacker can continuously send this malformed request to keep the device inaccessible to legitimate traffic.

Denial of Service vulnerability in Debut embedded httpd 1.20 in Brother DCP-J132W (and probably other DCP models) allows remote attackers to hang the printer (disrupting its network connection) by sending a large amount of HTTP packets.

Cross-site request forgery (CSRF) vulnerability in MFC-J960DWN firmware ver.D and earlier allows remote attackers to hijack the authentication of administrators via unspecified vectors.
