A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series allows an unauthenticated, network-based attacker to control certain, important environment variables.
Using a crafted request an attacker is able to modify
certain PHP environment variables leading to partial loss of integrity, which may allow chaining to other vulnerabilities.

Detection & IOCsextracted from sources · hover to see the quote
- →Monitor for POST requests to /webauth_operation.php with parameters 'rs=do_upload' and 'rsargs[]' containing base64-encoded payloads or .php/.ini file uploads — this is the primary attack vector for the exploit chain. ↗
- →Detect GET requests to /webauth_operation.php with a PHPRC query parameter pointing to /var/tmp/, indicating PHP environment variable manipulation for RCE. ↗
- →Alert on HTTP requests to J-Web (webauth_operation.php) that include 'auto_prepend_file' or 'allow_url_include' in POST body or query string, as these are used to achieve fileless RCE via the data:// protocol. ↗
- →Watch for references to /dev/fd/0 in HTTP requests targeting Juniper J-Web, which is used to read stdin as a pseudo-file for fileless code execution. ↗
- →Use Shodan query 'title:"Juniper Web Device Manager"' to identify internet-exposed Juniper J-Web interfaces for asset discovery and exposure assessment. ↗
- ·CVE-2023-36844 alone is rated 'medium' (CVSS 5.3), but when chained with CVE-2023-36845, CVE-2023-36846, and CVE-2023-36847, the combined exploit achieves critical unauthenticated RCE (CVSS 9.8). Detection and patching priority should reflect the chained severity, not the individual score. ↗
- ·VulnCheck demonstrated a single-CVE (CVE-2023-36845 only) fileless RCE variant using a single curl command, bypassing the need to upload files — detection rules requiring file upload activity may miss this newer variant. ↗
- ·The original watchTowr PoC required uploading two files (a .php and a .ini), but the VulnCheck variant achieves RCE without any file uploads using the data:// protocol — both attack patterns must be covered in detection logic. ↗
- ·Older Juniper SRX devices (e.g., SRX210) may lack the do_fileUpload() function, meaning the watchTowr file-upload exploit chain will not work on them, but the VulnCheck fileless variant may still apply. ↗

CVE-2024-21591 [CRITICAL] Juniper warns of critical RCE bug in its firewalls and switches
## Juniper warns of critical RCE bug in its firewalls and switches
## Sergiu Gatlan
Juniper Networks has released security updates to fix a critical pre-auth remote code execution (RCE) vulnerability in its SRX Series firewalls and EX Series switches.
Found in the devices' J-Web configuration interfaces and tracked as CVE-2024-21591, this critical security flaw can also be exploited by unauthenticated threat actors to get root privileges or launch denial-of-service (DoS) attacks against unpatched devices.
"This issue is caused by use of an insecure function allowing an attacker to overwrite arbitrary memory," the company explained in a security advisory published Wednesday.
At the moment, Juniper's Security Incident Response Team has no evidence that the vulnerability is being exploit

## CISA warns of actively exploited Juniper pre-auth RCE exploit chain
## Sergiu Gatlan
CISA warned federal agencies today to secure Juniper devices on their networks by Friday against four vulnerabilities now used in remote code execution (RCE) attacks as part of a pre-auth exploit chain.
The alert comes one week after Juniper updated its advisory to notify customers that the flaws found in Juniper's J-Web interface (tracked as CVE-2023-36844, CVE-2023-36845, CVE-2023-36846, and CVE-2023-36847) have been successfully exploited in the wild.
"Juniper SIRT is now aware of successful exploitation of these vulnerabilities. Customers are urged to immediately upgrade," the company said .

CVE-2023-36844 [MEDIUM] Thousands of Juniper devices vulnerable to unauthenticated RCE flaw
## Thousands of Juniper devices vulnerable to unauthenticated RCE flaw
## Bill Toulas
An estimated 12,000 Juniper SRX firewalls and EX switches are vulnerable to a fileless remote code execution flaw that attackers can exploit without authentication.
In August, Juniper disclosed numerous 'PHP environment variant manipulation' (CVE-2023-36844/CVE-2023-36845) and 'Missing Authentication for Critical Function' (CVE-2023-36846/CVE-2023-36847) vulnerabilities that by themselves only had a 'medium' severity rating of 5.3.
However, when chained together, these vulnerabilities became a critical remote code execution flaw with a rating of 9.8.
In a later technical report , watchTowr Labs released a PoC that chained the CVE-2023-36845 and CVE-2023-36846 flaws, allowing the researchers to remote

# Black Basta Ransomware: In-Depth Analysis, Detection, and Mitigation
## Summary of Black Basta Ransomware
Black Basta first emerged in early 2022. The ransomware family is an evolution of the Hermes/Ryuk/Conti families. Black Basta was heavily advertised in underground cybercrime markets. Black Basta practices double extortion – demanding payment for a decryptor, as well as for the non-release of stolen data. There are Windows and LInux variants of Black Basta ransomware. The group is responsible for hundreds of attacks against global targets of varying sectors.
February 2025 Update: Nearly a year’s worth of Black Basta chat logs have been released on Telegram, providing detailed insight into the groups operational workflow, reconnaissance activities, and specific userID and details o
