Vulnerabilidades

An off-by-one error (CWE-193) in the ConsumeUnit16Array and ConsumeUnit64Array functions in Velocidex Velociraptor before version 0.76.5 on Windows and Linux allows a local attacker to cause a Denial of Service (DoS) via a process crash by providing a specially crafted .evtx file to the parse_evtx VQL plugin.

Velociraptor versions prior to 0.76.4 contain a resource exhaustion vulnerability in the server's agent control channel. This allows a compromised or rogue Velociraptor client to crash the server via out-of-memory (OOM) by sending crafted messages through the normal client communication channel.

Velociraptor versions prior to 0.76.3 contain a vulnerability in the query() plugin which allows access to all orgs with the user's current ACL token. This allows an authenticated GUI user with access in one org, to use the query() plugin, in a notebook cell, to run VQL queries on other orgs which they may not have…

Rapid7 Velociraptor versions prior to 0.76.2 contain an improper input validation vulnerability in the client monitoring message handler on the Velociraptor server (primarily Linux) that allows an authenticated remote attacker to write to arbitrary internal server queues via a crafted monitoring message with a…

Rapid7 Velociraptor versions before 0.75.6 contain a directory traversal issue on Linux servers that allows a rogue client to upload a file which is written outside the datastore directory. Velociraptor is normally only allowed to write in the datastore directory. The issue occurs due to insufficient sanitization of…

Velociraptor allows collection of VQL queries packaged into Artifacts from endpoints. These artifacts can be used to do anything and usually run with elevated permissions. To limit access to some dangerous artifact, Velociraptor allows for those to require high permissions like EXECVE to launch. The…

An improper access control issue in the VQL shell feature in Velociraptor Versions < 0.73.4 allowed authenticated users to execute the execve() plugin in deployments where this was explicitly forbidden by configuring the prevent_execve flag in the configuration file. This setting is not usually recommended and is…

Rapid7 Velociraptor MSI Installer versions below 0.73.3 suffer from a vulnerability whereby it creates the installation directory with WRITE_DACL permission to the BUILTIN\\Users group. This allows local users who are not administrators to grant themselves the Full Control permission on Velociraptor's files. By…

Rapid7 Velociraptor versions prior to 0.7.0-4 suffer from a reflected cross site scripting vulnerability. This vulnerability allows attackers to inject JS into the error path, potentially leading to unauthorized execution of scripts within a user's web browser. This vulnerability is fixed in version 0.7.0-04 and a…

Due to insufficient validation in the PE and OLE parsers in Rapid7's Velociraptor versions earlier than 0.6.8 allows attacker to crash Velociraptor during parsing of maliciously malformed files. For this attack to succeed, the attacker needs to be able to introduce malicious files to the system at the same time that…

Rapid7 Velociraptor did not properly sanitize the client ID parameter to the CreateCollection API, allowing a directory traversal in where the collection task could be written. It was possible to provide a client id of "../clients/server" to schedule the collection for the server (as a server artifact), but only…

Rapid7 Velociraptor allows users to be created with different privileges on the server. Administrators are generally allowed to run any command on the server including writing arbitrary files. However, lower privilege users are generally forbidden from writing or modifying files on the server. The VQL copy() function…

The Velociraptor GUI contains an editor suggestion feature that can display the description field of a VQL function, plugin or artifact. This field was not properly sanitized and can lead to cross-site scripting (XSS). This issue was resolved in Velociraptor 0.6.5-2.

On MacOS and Linux, it may be possible to perform a symlink attack by replacing this predictable file name with a symlink to another file and have the Velociraptor client overwrite the other file. This issue was resolved in Velociraptor 0.6.5-2.

A cross-site scripting (XSS) issue in generating a collection report made it possible for malicious clients to inject JavaScript code into the static HTML file. This issue was resolved in Velociraptor 0.6.5-2.

Due to a bug in the handling of the communication between the client and server, it was possible for one client, already registered with their own client ID, to send messages to the server claiming to come from another client ID. This issue was resolved in Velociraptor 0.6.5-2.

Rapid7 Velociraptor 0.5.9 and prior is vulnerable to a post-authentication persistent cross-site scripting (XSS) issue, where an authenticated user could abuse MIME filetype sniffing to embed executable code on a malicious upload. This issue was fixed in version 0.6.0. Note that login rights to Velociraptor is nearly…

Unknown vulnerability in the DNSd proxy, as used in Symantec Gateway Security 5400 2.x and 5300 1.x, Enterprise Firewall 7.0.x and 8.x, and VelociRaptor 1100/1200/1300 1.5, allows remote attackers to poison the DNS cache and redirect users to malicious sites.

Buffer overflow in Entrust LibKmp ISAKMP library, as used by Symantec Enterprise Firewall 7.0 through 8.0, Gateway Security 5300 1.0, Gateway Security 5400 2.0, and VelociRaptor 1.5, allows remote attackers to execute arbitrary code via a crafted ISAKMP payload.

Symantec Raptor Firewall 6.5 and 6.5.3, Enterprise Firewall 6.5.2 and 7.0, VelociRaptor Models 500/700/1000 and 1100/1200/1300, and Gateway Security 5110/5200/5300 generate easily predictable initial sequence numbers (ISN), which allows remote attackers to spoof connections.

Memory leak in the (1) httpd, (2) nntpd, and (3) vpn driver in VelociRaptor 1.0 allows remote attackers to cause a denial of service (memory consumption) via an unknown method.

Multiple buffer overflows in Symantec Raptor Firewall 6.5 and 6.5.3, Enterprise Firewall 6.5.2 and 7.0, VelociRaptor 500/700/1000 and 1100/1200/1300, and Gateway Security 5110/5200/5300 allow remote attackers to cause a denial of service (service termination) via (1) malformed RealAudio (rad) packets that are not…

The web proxy component in Symantec Enterprise Firewall (SEF) 6.5.2 through 7.0, Raptor Firewall 6.5 and 6.5.3, VelociRaptor, and Symantec Gateway Security allow remote attackers to cause a denial of service (connection resource exhaustion) via multiple connection requests to domains whose DNS server is unresponsive…

FTP proxy in Symantec Raptor Firewall 6.5.3 and Enterprise 7.0 rewrites an FTP server's "FTP PORT" responses in a way that allows remote attackers to redirect FTP data connections to arbitrary ports, a variant of the "FTP bounce" vulnerability.
