An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2025-5777 in the wild since at least 10 Jul 2025, including in ransomware campaigns.\n\nAffected product: NetScaler ADC. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-5777/ (Markdown: https://insights.sbomify.com/CVE-2025-5777/index.md)","id":"CVE-2025-5777","markdown":"https://insights.sbomify.com/CVE-2025-5777/index.md","name":"CVE-2025-5777","record":{"aliases":["GHSA-29vj-j5w5-pcph"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"NetScaler ADC Gateway","requires_auth":"none","summary":"Attackers can read sensitive memory contents when NetScaler is configured as a Gateway or AAA virtual server due to insufficient input validation.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Citrix","cpe":[{"product":"netscaler_application_delivery_controller","vendor":"citrix"},{"product":"netscaler_gateway","vendor":"citrix"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Insufficient input validation leading to memory overread when the NetScaler is configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) OR AAA virtual server","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2025-06-30","github_poc":26,"max_poc_stars":50,"metasploit":0,"nuclei":1,"refs":[{"date":"2025-07-08T14:12:45Z","kind":"github_poc","ref":"https://github.com/win3zz/CVE-2025-5777","stars":50,"title":"CVE-2025-5777 (CitrixBleed 2) - Critical memory leak vulnerability affecting Citrix NetScaler ADC and Gateway devices"},{"date":"2025-07-10T07:15:07Z","kind":"github_poc","ref":"https://github.com/bughuntar/CVE-2025-5777","stars":31,"title":"CVE-2025-5777 Citrix NetScaler Memory Leak Exploit (CitrixBleed 2)"},{"date":"2025-06-30T11:02:46Z","kind":"github_poc","ref":"https://github.com/mingshenhk/CitrixBleed-2-CVE-2025-5777-PoC-","stars":17,"title":"详细讲解CitrixBleed 2 — CVE-2025-5777（越界泄漏）PoC 和检测套件"},{"date":"2025-07-08T10:27:16Z","kind":"github_poc","ref":"https://github.com/Chocapikk/CVE-2025-5777","stars":7,"title":"CitrixBleed 2 (CVE-2025-5777)"},{"date":"2025-08-07T20:47:54Z","kind":"github_poc","ref":"https://github.com/soltanali0/CVE-2025-5777-Exploit","stars":5,"title":null},{"date":"2025-07-23T12:05:05Z","kind":"github_poc","ref":"https://github.com/Shivshantp/CVE-2025-5777-TrendMicro-ApexCentral-RCE","stars":4,"title":"PoC for CVE-2025-5777 – Auth Bypass and RCE in Trend Micro Apex Central"},{"date":"2025-07-05T23:56:36Z","kind":"github_poc","ref":"https://github.com/nocerainfosec/cve-2025-5777","stars":3,"title":"Memory disclosure vulnerability in Citrix NetScaler ADC and Gateway when configured as a Gateway (VPN virtual server, ICA proxy, CVPN, RDP Proxy)."},{"date":"2025-07-15T17:49:38Z","kind":"github_poc","ref":"https://github.com/cyberleelawat/ExploitVeer","stars":3,"title":"An advanced, powerful, and easy-to-use tool designed to detect and exploit CVE-2025-5777 (CitrixBleed 2).
