An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-0765 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- System.Security.Cryptography.Xml (NuGet): affected all versions; fixed in 4.4.2\n- System.Security.Cryptography.Xml (NuGet): affected all versions; fixed in 4.4.2\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-2018-0765/ (Markdown: https://insights.sbomify.com/CVE-2018-0765/index.md)","id":"CVE-2018-0765","markdown":"https://insights.sbomify.com/CVE-2018-0765/index.md","name":"CVE-2018-0765","record":{"aliases":["GHSA-35hc-x2cw-2j4v"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":".NET Framework","requires_auth":"none","summary":"Attackers can cause denial of service in .NET applications by sending malicious XML documents due to improper processing.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net_core","vendor":"microsoft"},{"product":".net_framework","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A denial of service vulnerability exists when .NET and .NET Core improperly process XML documents, aka \".NET and .NET Core Denial of Service Vulnerability.\" This affects Microsoft .NET Framework 2.0, Microsoft .NET Framework 3.0, Microsoft .NET Framework 4.7.1, Microsoft .NET Framework 4.6/4.6.1/4.6.2/4.7/4.7.1, Microsoft .NET Framework 4.5.2, Microsoft .NET Framework 4.7/4.7.1, Microsoft .NET Framework 4.6, Microsoft .NET Framework 3.5, Microsoft .NET Framework 3.5.1, Microsoft .NET Framework 4.6/4.6.1/4.6.2, Microsoft .NET Framework 4.6.2/4.7/4.7.1, .NET Core 2.0, Microsoft .NET Framework 4.7.2.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service vulnerability exists when .NET and .NET Core improperly process XML documents","id":"CVE-2018-0765","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":"microsoft:.net_framework","products":["microsoft:.net_framework"],"type":"xxe","year":"2018"},"n_packages":2,"n_references":3,"next":{"headline":"Information disclosure in Microsoft Edge","id":"CVE-2018-0766"},"packages":[{"ecosystem":"NuGet","fixed":["4.4.2"],"introduced":["0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":null,"source":"GHSA-35hc-x2cw-2j4v"},{"ecosystem":"NuGet","fixed":["4.4.2"],"introduced":["0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":"pkg:nuget/System.Security.Cryptography.Xml","source":"GHSA-35hc-x2cw-2j4v"}],"prev":{"headline":"Denial of service vulnerability exists when .NET and .NET Core improperly process XML documents","id":"CVE-2018-0764"},"products":["n/a"],"published":"2018-05-09","related":[{"cvss_score":7.8,"headline":"Microsoft .NET Framework, SharePoint, and Visual Studio Remote Code Execution","id":"CVE-2020-1147","kev_date_added":"2021-11-03","published":"2020-07-14"},{"cvss_score":8.8,"headline":"Code injection in .NET Core","id":"CVE-2020-0605","kev_date_added":null,"published":"2020-01-14"},{"cvss_score":8.8,"headline":"Remote code execution in Microsoft.WindowsDesktop.App.Ref","id":"CVE-2020-0606","kev_date_added":null,"published":"2020-01-14"},{"cvss_score":7.5,"headline":"High severity vulnerability that affects System.Management.Automation","id":"CVE-2019-1301","kev_date_added":null,"published":"2019-09-11"},{"cvss_score":7.5,"headline":"Regular Expression Denial of Service in System.Text.RegularExpressions","id":"CVE-2019-0820","kev_date_added":null,"published":"2019-05-16"},{"cvss_score":7.5,"headline":"Denial of service in ASP.NET Core","id":"CVE-2019-0980","kev_date_added":null,"published":"2019-05-16"},{"cvss_score":7.5,"headline":"Denial of service in ASP.NET Core","id":"CVE-2019-0981","kev_date_added":null,"published":"2019-05-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can cause denial of service in .NET applications by sending malicious XML documents due to improper processing.","url":"https://insights.sbomify.com/CVE-2018-0765/"}
