Vulnerability Description

A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series

and SRX Series

allows an unauthenticated, network-based attacker to remotely execute code.

Using a crafted request which sets the variable PHPRC an attacker is able to modify the PHP execution environment allowing the injection und execution of code.

This issue affects Juniper Networks Junos OS on EX Series

and

SRX Series:

All versions prior to

20.4R3-S9;

21.1 versions 21.1R1 and later;
21.2 versions prior to 21.2R3-S7;
21.3 versions prior to 21.3R3-S5;
21.4 versions prior to 21.4R3-S5;
22.1 versions

prior to

22.1R3-S4;

22.2 versions

prior to

22.2R3-S2;

22.3 versions

prior to

22.3R2-S2, 22.3R3-S1;

22.4 versions

prior to

22.4R2-S1, 22.4R3;

23.2 versions prior to 23.2R1-S1, 23.2R2.

Recommended Actions

Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (344360 , 390709 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.
Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.
- Affected versions: Juniper Networks Junos OS versions earlier than 20.4R3-S9.
- Affected versions: Juniper Networks Junos OS versions earlier than 21.1*.
- Affected versions: Juniper Networks Junos OS versions earlier than 21.2R3-S7.
- Affected versions: Juniper Networks Junos OS versions earlier than 21.3R3-S5.
- Affected versions: Juniper Networks Junos OS versions earlier than 21.4R3-S5.
- Affected versions: Juniper Networks Junos OS versions earlier than 22.1R3-S4.
- Affected versions: Juniper Networks Junos OS versions earlier than 22.2R3-S2.
- Affected versions: Juniper Networks Junos OS versions earlier than 22.3R2-S2, 22.3R3-S1.
- Affected versions: Juniper Networks Junos OS versions earlier than 22.4R2-S1, 22.4R3.
- Affected versions: Juniper Networks Junos OS versions earlier than 23.2R1-S1, 23.2R2.
- No specific CNA/vendor solution or workaround is included in the current CVE Record (opens in a new tab) . Review the vendor’s security advisories and supported-release guidance before making changes.
- CISA KEV required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- CISA KEV federal remediation due date: 2023-11-17
Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
