An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-30116 in the wild since at least 3 Nov 2021, including in ransomware campaigns.\n\nAffected product: n/a. 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-2021-30116/ (Markdown: https://insights.sbomify.com/CVE-2021-30116/index.md)","id":"CVE-2021-30116","markdown":"https://insights.sbomify.com/CVE-2021-30116/index.md","name":"CVE-2021-30116","record":{"aliases":["GHSA-qm28-hjhx-pwqg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kaseya VSA","requires_auth":"none","summary":"Attackers can extract agent credentials from a public download page to obtain session cookies, bypassing authentication and accessing sensitive system data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vsa_agent","vendor":"kaseya"},{"product":"vsa_server","vendor":"kaseya"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"Kaseya VSA before 9.5.7 allows credential disclosure, as exploited in the wild in July 2021. By default Kaseya VSA on premise offers a download page where the clients for the installation can be downloaded. The default URL for this page is https://x.x.x.x/dl.asp When an attacker download a client for Windows and installs it, the file KaseyaD.ini is generated (C:\\Program Files (x86)\\Kaseya\\XXXXXXXXXX\\KaseyaD.ini) which contains an Agent_Guid and AgentPassword This Agent_Guid and AgentPassword can be used to log in on dl.asp (https://x.x.x.x/dl.asp?un=840997037507813\u0026pw=113cc622839a4077a84837485ced6b93e440bf66d44057713cb2f95e503a06d9) This request authenticates the client and returns a sessionId cookie that can be used in subsequent attacks to bypass authentication. Security issues discovered --- * Unauthenticated download page leaks credentials * Credentials of agent software can be used to obtain a sessionId (cookie) that can be used for services not intended for use by agents * dl.asp accepts credentials via a GET request * Access to KaseyaD.ini gives an attacker access to sufficient information to penetrate the Kaseya installation and its clients. Impact --- Via the page /dl.asp enough information can be obtained to give an attacker a sessionId that can be used to execute further (semi-authenticated) attacks against the system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-30116.yaml","stars":null,"title":"Kaseya VSA \u003c 9.5.7 - Credential Disclosure via Windows Agent"}],"tier":"exploited"},"has_fix":null,"headline":"Kaseya Virtual System/Server Administrator (VSA) Information Disclosure","id":"CVE-2021-30116","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2021-11-17","knownRansomwareCampaignUse":"Known","product":"Virtual System/Server Administrator (VSA)","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Kaseya","vulnerabilityName":"Kaseya Virtual System/Server Administrator (VSA) Information Disclosure Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Authenticated SQL injection in Kaseya VSA \u003c v9.5.6","id":"CVE-2021-30117"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2021-30114"},"products":["n/a"],"published":"2021-07-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["n/a"]},"summary":"Attackers can extract agent credentials from a public download page to obtain session cookies, bypassing authentication and accessing sensitive system data.","url":"https://insights.sbomify.com/CVE-2021-30116/"}
