Cybersecurity company Huntress on Friday warned of "widespread compromise" of SonicWall SSL VPN devices to access multiple customer environments. "Threat actors are authenticating into multiple accounts rapidly across compromised devices," it said. "The speed and scale of these attacks imply that the attackers appear to control valid credentials rather than brute-forcing." A significant chunk of
Threat actors are abusing Velociraptor, an open-source digital forensics and incident response (DFIR) tool, in connection with ransomware attacks likely orchestrated by Storm-2603 (aka CL-CRI-1040 or Gold Salem), which is known for deploying the Warlock and LockBit ransomware. The threat actor's use of the security utility was documented by Sophos last month. It's assessed that the attackers
# Escape of VM Context gives access to process level functionality ## Summary Happy DOM v19 and lower contains a security vulnerability that puts the owner system at the risk of RCE (Remote Code Execution) attacks. A Node.js VM Context is not an isolated environment, and if the user runs untrusted JavaScript code within the Happy DOM VM Context, it may escape the VM and get access to process level functionality. What the attacker can get control over depends on if the process is using ESM or CommonJS. With CommonJS the attacker can get hold of the `require()` function to import modules. Happy DOM has JavaScript evaluation enabled by default. This may not be obvious to the consumer of Happy DOM and can potentially put the user at risk if untrusted code is executed within the environment. ## Reproduce ### CommonJS (Possible to get hold of require) ```javascript const { Window } = require('happy-dom'); const window = new Window({ console }); window.document.write(` <script> ...
### Impact A vulnerable node can be made to consume very large amounts of memory when handling specially crafted p2p messages sent from an attacker node. In order to carry out the attack, the attacker establishes a peer connections to the victim, and sends a malicious `GetBlockHeadersRequest` message with a `count` of `0`, using the `Parallax` protocol. In `descendants := chain.GetHeadersFrom(num+count-1, count-1)`, the value of `count-1` is passed to the function `GetHeadersFrom(number, count uint64)` as parameter `count`. Due to integer overflow, `UINT64_MAX` value is then passed as the `count` argument to function `GetHeadersFrom(number, count uint64)`. This allows an attacker to bypass `maxHeadersServe` and request all headers from the latest block back to the genesis block. ### Patches The fix has been included in the Parallax client version `0.1.4` and onwards. The vulnerability was patched in: https://github.com/microstack-tech/parallax/commit/f759e9090aaf00a43c616d7cbd133...
### Summary The ReadFileTool in Flowise does not restrict file path access, allowing authenticated attackers to exploit this vulnerability to read arbitrary files from the file system, potentially leading to remote command execution. ### Details Flowise supports providing ReadFileTool for large models to read files in the server's file system. The implementation of this tool is located at packages/components/nodes/tools/ReadFile/ReadFile.ts. ``` /** * Class for reading files from the disk. Extends the StructuredTool * class. */ export class ReadFileTool extends StructuredTool { static lc_name() { return 'ReadFileTool' } schema = z.object({ file_path: z.string().describe('name of file') }) as any name = 'read_file' description = 'Read file from disk' store: BaseFileStore constructor({ store }: ReadFileParams) { super(...arguments) this.store = store } async _call({ file_path }: z.infer<typeof this.sche...
A vulnerability in Allstar’s Reviewbot component caused inbound webhook requests to be validated against a hard-coded, shared secret: https://github.com/ossf/allstar/blob/294ae985cc2facd0918e8d820e4196021aa0b914/pkg/reviewbot/reviewbot.go#L59 The value used for the secret token was compiled into the Allstar binary and could not be configured at runtime. In practice, this meant that every deployment using Reviewbot would validate requests with the same secret unless the operator modified source code and rebuilt the component - an expectation that is not documented and is easy to miss. While Reviewbot is not commonly enabled in standard Allstar setups, we are issuing this advisory to reach any environments where it may have been deployed. ## Affected Versions All Allstar releases prior to v4.5 that include the Reviewbot code path are affected. Deployments on v4.5 and later are not affected. If you have not enabled or exposed the Reviewbot endpoint, this issue does not apply to your i...
### Summary The sanitization method `ldap.filter.escape_filter_chars` can be tricked to skip escaping of special characters when a crafted `list` or `dict` is supplied as the `assertion_value` parameter, and the non-default `escape_mode=1` is configured. ### Details The method `ldap.filter.escape_filter_chars` supports 3 different escaping modes. `escape_mode=0` (default) and `escape_mode=2` happen to raise exceptions when a `list` or `dict` object is supplied as the `assertion_value` parameter. However, `escape_mode=1` happily computes without performing adequate logic to ensure a fully escaped return value. ### PoC ``` >>> import ldap.filter ``` **Exploitable** ``` >>> ldap.filter.escape_filter_chars(["abc@*()/xyz"], escape_mode=1) 'abc@*()/xyz' >>> ldap.filter.escape_filter_chars({"abc@*()/xyz": 1}, escape_mode=1) 'abc@*()/xyz' ``` **Not exploitable** ``` >>> ldap.filter.escape_filter_chars("abc@*()/xyz", escape_mode=1) 'abc@\\2a\\28\\29\\2fxyz' >>> ldap.filter.escape_filter_chars...
Cross-site request forgery (CSRF) vulnerability in Liferay Portal 7.4.1 through 7.4.3.112, and Liferay DXP 2023.Q4.0 through 2023.Q4.5, 2023.Q3.1 through 2023.Q3.10, and 7.4 GA through update 92 allows remote attackers to add and edit publication comments.
An authenticated stored XSS vulnerability exists in the Bagisto 2.3.6 admin panel's product creation path, allowing an attacker to upload a crafted SVG file containing malicious JavaScript code. This vulnerability can be exploited by an authenticated admin user to execute arbitrary JavaScript in the browser, potentially leading to session hijacking, data theft, or unauthorized actions.
### Summary There is a denial of service vulnerability in the `If-Match` and `If-None-Match` header parsing component of Sinatra, if the `etag` method is used when constructing the response and you are using Ruby < 3.2. ### Details Carefully crafted input can cause `If-Match` and `If-None-Match` header parsing in Sinatra to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is typically involved in generating the `ETag` header value. Any applications that use the `etag` method when generating a response are impacted if they are using Ruby below version 3.2. ### Resources * https://github.com/sinatra/sinatra/issues/2120 (report) * https://github.com/sinatra/sinatra/pull/2121 (fix) * https://github.com/sinatra/sinatra/pull/1823 (older ReDoS vulnerability) * https://bugs.ruby-lang.org/issues/19104 (fix in Ruby >= 3.2)
