Exploitation of CitrixBleed 2 (CVE-2025-5777) Began Before PoC Was Public

GreyNoise has observed active exploitation attempts against CVE-2025-5777 (CitrixBleed 2), a memory overread vulnerability in Citrix NetScaler. Exploitation began on June 23 — nearly two weeks before a public proof-of-concept (PoC) was released on July 4. 

We created a tag on July 7 to track this activity. Because GreyNoise retroactively associates pre-tag traffic with new tags, prior exploitation attempts are now visible in the GreyNoise Visualizer. 

‍

Key Observations

  • First observed activity: June 23, 2025
  • PoC released: July 4, 2025
  • GreyNoise tag published: July 7, 2025
  • CISA confirms activity with GreyNoise: July 9, 2025 (prior to KEV addition) 

‍

BLOCK MALICIOUS IPS

‍

‍

Targeted Behavior 

Early exploitation attempts came from malicious IPs geolocated in China. Rather than exploiting indiscriminately, these IPs targeted GreyNoise sensors configured to emulate Citrix NetScaler appliances, suggesting deliberate targeting. 

‍

CISA Confirmation 

On July 9, shortly after we published the tag, CISA contacted GreyNoise to confirm exploitation activity. CVE-2025-5777 was subsequently added to the Known Exploited Vulnerabilities (KEV) catalog. 

‍

Recommended Actions

Defenders can dynamically block malicious IPs to reduce exposure and suppress alerts. 

‍

BLOCK MALICIOUS IPS

‍

The above list will stay updated as new IPs are observed attempting to exploit CVE-2025-5777.

A Patchy Server: GreyNoise observes Path Traversal and Remote Code Execution in Apache HTTP Server (CVE-2021-41773)

Path Traversal and Remote Code Execution in Apache HTTP Server, CVE-2021-41773

On October 4th, 2021, Apache disclosed a path traversal vulnerability CVE-2021-41773 that affects HTTP Server version 2.4.49. The vulnerability was introduced in this version (2.4.49) and is patched in version 2.4.50.

This path traversal vulnerability allows sensitive files outside of the expected document root to be accessed, such as configuration files and Common Gateway Interface (CGI) scripts. This allows for specially crafted requests to read arbitrary files as well as perform Remote Code Execution (RCE) on systems that have the Apache “mod_cgi” module enabled.

On October 3rd, 2021, at 08:44 UTC, GreyNoise observed the first scan for this vulnerability from 36.68.53.196. This predates the mailing list announcement from Apache on October 5th as well as the release of 2.4.50 on October 4th, but after the patch was committed on September 29th. [View 36.68.53.196 in GreyNoise]

As of October 5th, 2021, the first Proof of Concept (POC) code became available which demonstrated arbitrary file read. It was closely followed by a POC demonstrating RCE.

GreyNoise Identifies Vulnerability Checks of VMWare vCenter Remote File Upload (CVE-2021-22005)

On September 21, 2021, VMWare published an advisory for several vulnerabilities. This included, most notably, CVE-2021-22005, which affects their vCenter Server product. This vulnerability is an arbitrary file upload vulnerability that can lead to remote code execution (RCE) via upload of a specially crafted file. This works regardless of the configuration settings of vCenter Server.

Due to the severity of this vulnerability, VMWare published workaround instructions detailing how to manually or automatically patch the affected products. The automated patching script (available in the right-hand panel in the link above) includes logic to validate if your product is vulnerable to CVE-2021-22005, as well as confirm the patch has worked as expected.

As of September 23, 2021, there is no known publicly available proof-of-concept (PoC) code for the CVE that enables arbitrary file upload or RCE. However, GreyNoise is observing a significant number of checks for vulnerable instances of vCenter Server based off of the automated patching script provided by VMWare, most of these egressing via Tor.

The following tags have been released to enable monitoring of relevant activity:

GreyNoise Identifies Vulnerability Checks of Exchange ProxyShell (CVE-2021-34473)

During BlackHat 2021, security researcher Orange Tsai demonstrated a proof-of-concept exploit for Microsoft Exchange vulnerabilities, including a Pre-auth Path Confusion leading to Access-Control List (ACL) bypass (tracked as CVE-2021-34473, also called ProxyShell). Since Tsai’s talk, multiple researchers have published write-ups about the vulnerabilities [1, 2]. GreyNoise had not observed any mass scanning activity until Aug. 9, and has seen a significant uptick in scanning as of Thursday, Aug. 12. GreyNoise has created two tags to track activity related to these vulnerabilities.

Figure 1: ProxyShell activity as seen by GreyNoise over time

Exchange ProxyShell Vuln Check: The vulnerability check for CVE-2021-34473 has several public variations. These include checking for access to /mapi/nspi which results in exposure of potentially sensitive information such as Version, User, UPN, SID, and Organization. Out of caution, GreyNoise tags this as malicious intent despite being a Vuln Check. [View In GreyNoise]

Exchange ProxyShell Vuln Attempt: Active attempts that leverage and chain the Pre-Auth Path Confusion for further exploitation through Elevation of Privilege on Exchange PowerShell Backend (CVE-2021-34523) or Post-auth Arbitrary-File-Write leading to remote code execution (CVE-2021-31207) are included in this tag. [View In GreyNoise]

Editor's Note: If either of these tags, or any tags for that matter, return "no results," this means that we have not observed any recent activity. You can be notified if this changes by using our Alerts feature.

Removed Tags

These tags have been removed because they no longer exist, scan, and/or can no longer be accurately identified

  • RDP Bruteforcer
  • Windows RDP Cookie Hijacker
  • RDP Scanner

Multiple RDP tags have been deprecated in favor of RDP Crawler, which more accurately accounts for much of the behavior we see. We are currently working to create more accurate and narrowly scoped tags for RDP scanning and exploitation.

The RDP Bruteforcer tag was created around the same time as BlueKeep and aggressively assigned `malicious` intent to basic RDP connection attempts. After re-evaluating this, we feel this was incorrect and have taken actions to improve our RDP tags in general.
