    Overview

    The vulnerability CVE-2025-59942, a critical issue affecting the Golang implementation of Fast Finality for Filecoin (go-f3), has notable implications for Filecoin nodes. This vulnerability is due to a flaw in versions 0.8.6 and below, where ‘poison’ messages can induce a panic in go-f3, leading to potential system compromise or data leakage.

    Vulnerability Summary

    CVE ID: CVE-2025-59942
    Severity: High (7.5)
    Attack Vector: Network
    Privileges Required: Low
    User Interaction: None
    Impact: System compromise or data leakage

    Affected Products

    Product | Affected Versions

    go-f3 | 0.8.6 and below

    How the Exploit Works

    The vulnerability resides in the validation process of go-f3, where a specific type of poison message can cause an integer overflow in the signer index validation. This results in the node crashing. An attacker can exploit this vulnerability by directly sending the poison message to the target, which doesn’t require any user interaction. The message is not self-propagating as the bug lies within the validator.

    Conceptual Example Code

    Here’s a conceptual example of how the vulnerability might be exploited. This pseudocode represents a ‘poison’ message being sent to a node.

    package main
    import (
    "net"
    "log"
    "fmt"
    )
    func main() {
    conn, err := net.Dial("tcp", "target.node.com:port")
    if err != nil {
    log.Fatal("Connection failed: ", err.Error())
    }
    // Crafting the poison message
    msg := fmt.Sprintf("{\"signer_index\": %d}", 1<<31)
    _, err = conn.Write([]byte(msg))
    if err != nil {
    log.Fatal("Failed to send poison message: ", err.Error())
    }
    }

    This code attempts to connect to the target node and send a crafted poison message that would cause an integer overflow and crash the node.

    Attack Vector: Network
    Privileges Required: None
    User Interaction: None
    Impact: Potential system compromise or data leakage due to lack of access checking in the FreshRSS_Auth::hasAccess() function

    Affected Products

    Product | Affected Versions

    FreshRSS | 1.26.3 and below

    How the Exploit Works

    The vulnerability arises due to a lack of access checking in the FreshRSS_Auth::hasAccess() function used by some of the tag/feed related endpoints. FreshRSS controllers usually have a defined firstAction() method with an override to make sure that every action requires access. However, when this method is not defined, each action must manually check for access. The vulnerability is exploited when certain endpoints neither use the firstAction() method nor perform a manual access check, thereby exposing sensitive information.

    Conceptual Example Code

    Here is a conceptual example of how the vulnerability might be exploited. This hypothetical HTTP request targets an unprotected endpoint:

    GET /feed/endpoint HTTP/1.1
    Host: target.example.com

    This request could potentially expose sensitive information about feeds and tags of default admin users due to the lack of access control checks.
    Please note that this example is purely theoretical and is provided to assist in understanding the nature of the vulnerability.
