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-2015-8557 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pygments (PyPI): affected from 1.2.2; fixed in 2.1\n- pygments (PyPI): affected from 1.2.2; fixed in 2.1\n- Pygments (PyPI): affected from 1.2.2; fixed in 2.1\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-2015-8557/ (Markdown: https://insights.sbomify.com/CVE-2015-8557/index.md)","id":"CVE-2015-8557","markdown":"https://insights.sbomify.com/CVE-2015-8557/index.md","name":"CVE-2015-8557","record":{"aliases":["DEBIAN-CVE-2015-8557","DLA-369-1","DSA-3445-1","GHSA-fff8-4w9p-7v76","MGASA-2015-0478","PYSEC-2016-32","UBUNTU-CVE-2015-8557","USN-2862-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Pygments syntax highlighter","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands via shell metacharacters in font names processed by the Pygments library.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"pygments","vendor":"pygments"}],"cvss":{"score":9,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"The FontManager._get_nix_font_path function in formatters/img.py in Pygments 1.2.2 through 2.0.2 allows remote attackers to execute arbitrary commands via shell metacharacters in a font name.","ecosystems":["PyPI"],"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":"Command Injection in Pygments","id":"CVE-2015-8557","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux"],"type":"command_injection","year":"2015"},"n_packages":3,"n_references":9,"next":{"headline":"Denial of service in n/a","id":"CVE-2015-8558"},"packages":[{"ecosystem":"PyPI","fixed":["2.1"],"introduced":["1.2.2"],"last_affected":[],"package":"Pygments","purl":null,"source":"GHSA-fff8-4w9p-7v76"},{"ecosystem":"PyPI","fixed":["2.1"],"introduced":["1.2.2"],"last_affected":[],"package":"pygments","purl":"pkg:pypi/pygments","source":"GHSA-fff8-4w9p-7v76"},{"ecosystem":"PyPI","fixed":["2.1"],"introduced":["1.2.2"],"last_affected":[],"package":"pygments","purl":"pkg:pypi/pygments","source":"PYSEC-2016-32"}],"prev":{"headline":"Race condition in n/a","id":"CVE-2015-8556"},"products":["n/a"],"published":"2016-01-08","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary commands via shell metacharacters in font names processed by the Pygments library.","url":"https://insights.sbomify.com/CVE-2015-8557/"}
