The Bitdefender Napoca bare-metal hypervisor contains an out-of-bounds write vulnerability in the real-mode hook handler, implemented in napoca/kernel/handler.c. The handler uses a guest-controlled SS:SP-derived offset as an index into the 1MB RealModeMemory buffer without bounds validation. With SS=0xFFFF and ESP=0xFFFF, the computed offset can reach 0x10FFEF, exceeding the RealModeMemory buffer by 65,519 bytes. The IRET frame push can therefore write past the end of the buffer into the hypervisor heap. The product is end-of-life and unsupported when assigned.
Bitdefender Napoca bare-metal hypervisor contains an out-of-bounds write vulnerability in the BIOS INT 0x15 / E820 memory map handler, implemented in napoca/guests/bios_handlers.c. The handler computes a destination offset into the guest RealModeMemory buffer from guest-controlled ES and EDI register values without validating that the resulting address remains within the 1MB RealModeMemory allocation. A malicious guest operating in real mode can trigger the issue by invoking INT 0x15 with AX=0xE820, EDX=0x534D4150, ECX greater than or equal to 20, EBX=0, ES=0xFFFF, and EDI=0xFFFF. This can cause a write of up to 20 bytes past the end of the RealModeMemory buffer into the hypervisor heap. The product is end-of-life and unsupported when assigned.
A local privilege escalation vulnerability in Bitdefender Total Security versions prior to 27.0.47.241 allows low-privileged attackers to elevate privileges. The issue arises from bdservicehost.exe deleting files from a user-writable directory (C:\ProgramData\Atc\Feedback) without proper symbolic link validation, enabling arbitrary file deletion. This issue is chained with a file copy operation during network events and a filter driver bypass via DLL injection to achieve arbitrary file copy and code execution as elevated user.
An improper access restriction to a folder in Bitdefender Endpoint Security Tools for Mac (BEST) before 7.20.52.200087 allows local users with administrative privileges to bypass the configured uninstall password protection. An unauthorized user with sudo privileges can manually remove the application directory (/Applications/Endpoint Security for Mac.app/) and the related directories within /Library/Bitdefender/AVP without needing the uninstall password.
A Cross-Site Scripting (XSS) vulnerability has been identified in Psono-Client’s handling of vault entries of type website_password and bookmark, as used in Bitdefender SecurePass. The client does not properly sanitize the URL field in these entries. As a result, an attacker can craft a malicious vault entry (or trick a user into creating or importing one) with a javascript:URL. When the user interacts with this entry (for example, by clicking or opening it), the application will execute the malicious JavaScript in the context of the Psono vault. This allows an attacker to run arbitrary code in the victim’s browser, potentially giving them access to the user’s password vault and sensitive data.
A server-side request forgery (SSRF) vulnerability exists in the Bitdefender GravityZone Update Server when operating in Relay Mode. The HTTP proxy component on port 7074 uses a domain allowlist to restrict outbound requests, but fails to properly sanitize hostnames containing null-byte (%00) sequences. By crafting a request to a domain such as evil.com%00.bitdefender.com, an attacker can bypass the allowlist check, causing the proxy to forward requests to arbitrary external or internal systems.
A vulnerability in the sendMailFromRemoteSource method in Emails.php as used in Bitdefender GravityZone Console unsafely uses php unserialize() on user-supplied input without validation. By crafting a malicious serialized payload, an attacker can trigger PHP object injection, perform a file write, and gain arbitrary command execution on the host system.
A server-side request forgery (SSRF) vulnerability in Bitdefender GravityZone Console allows an attacker to bypass input validation logic using leading characters in DNS requests. Paired with other potential vulnerabilities, this bypass could be used for execution of third party code. This issue affects GravityZone Console: before 6.41.2.1.
Bitdefender Box, versions 1.3.11.490 through 1.3.11.505, uses the insecure HTTP protocol to download assets over the Internet to update and restart daemons and detection rules on the devices. Updates can be remotely triggered through the /set_temp_token API method. Then, an unauthenticated and network-adjacent attacker can use man-in-the-middle (MITM) techniques to return malicious responses. Restarted daemons that use malicious assets can then be exploited for remote code execution on the device.
A command injection vulnerability exists in the /check_image_and_trigger_recovery API endpoint of Bitdefender Box 1 (firmware version 1.3.11.490). This flaw allows an unauthenticated, network-adjacent attacker to execute arbitrary commands on the device, potentially leading to full remote code execution (RCE).
An improper access control vulnerability exists in Bitdefender Box 1 (firmware version 1.3.52.928 and below) that allows an unauthenticated attacker to downgrade the device's firmware to an older, potentially vulnerable version of a Bitdefender-signed firmware. The attack requires Bitdefender BOX to be booted in Recovery Mode and that the attacker be present within the WiFi range of the BOX unit.
An untrusted search path vulnerability in testinitsigs.exe as used in Bitdefender Antivirus Free 2020 allows a low-privilege attacker to execute code as SYSTEM via a specially crafted DLL file.
A vulnerability in the BitdefenderVirusScanner binary as used in Bitdefender Virus Scanner for MacOS may allow .dynamic library injection (DYLD injection) without being blocked by AppleMobileFileIntegrity (AMFI). This issue is caused by the absence of Hardened Runtime or Library Validation signing. This issue affects Bitdefender Virus Scanner versions before 3.18.
A vulnerability has been identified in Bitdefender Total Security HTTPS scanning functionality where the software trusts a certificate issued by an entity that isn't authorized to issue certificates. This occurs when the "Basic Constraints" extension in the certificate indicates that it is meant to be an "End Entity”. This flaw could allow an attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and potentially altering communications between the user and the website.
A vulnerability has been identified in Bitdefender Safepay's handling of HTTPS connections. The issue arises when the product blocks a connection due to an untrusted server certificate but allows the user to add the site to exceptions, resulting in the product trusting the certificate for subsequent HTTPS scans. This vulnerability allows an attacker to perform a Man-in-the-Middle (MITM) attack by using a self-signed certificate, which the product will trust after the site has been added to exceptions. This can lead to the interception and potential alteration of secure communications.
A vulnerability has been discovered in Bitdefender Total Security HTTPS scanning functionality that results in the improper trust of certificates issued using the DSA signature algorithm. The product does not properly check the certificate chain, allowing an attacker to establish MITM SSL connections to arbitrary sites using a DSA-signed certificate.
A vulnerability has been discovered in Bitdefender Total Security HTTPS scanning functionality that results in the improper trust of self-signed certificates. The product is found to trust certificates signed with the RIPEMD-160 hashing algorithm without proper validation, allowing an attacker to establish MITM SSL connections to arbitrary sites.
A vulnerability has been identified in Bitdefender Total Security HTTPS scanning functionality where the software fails to properly validate website certificates. Specifically, if a site certificate lacks the "Server Authentication" specification in the Extended Key Usage extension, the product does not verify the certificate's compliance with the site, deeming such certificates as valid. This flaw could allow an attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and potentially altering communications between the user and the website.
A vulnerability has been identified in the Bitdefender Total Security HTTPS scanning functionality where the product incorrectly checks the site's certificate, which allows an attacker to make MITM SSL connections to an arbitrary site. The product trusts certificates that are issued using the MD5 and SHA1 collision hash functions which allow attackers to create rogue certificates that appear legitimate.
A verbose error handling issue in the proxy service implemented in the GravityZone Update Server allows an attacker to cause a server-side request forgery. This issue only affects GravityZone Console versions before 6.38.1-5 running only on premise.
