Due to improper sanitization of web app properties (such as name, description, shortcuts), web apps were able to inject additional lines into XDG Desktop Entries (on Linux) and `AppInfo.ini` (on PortableApps.com). This allowed malicious web apps to introduce keys like `Exec`, which could run arbitrary code when the affected web app was launched. This vulnerability affects all Linux and PortableApps.com users of all PWAsForFirefox versions up to (excluding) 2.12.0. Windows and macOS users are not affected. This vulnerability has been fixed in commit `9932d4b` which has been included in release in v2.12.0. The main fix is implemented in the native part, but the extension also contains additional fixes. All Linux and PortableApps.com users are advised to update to this version as soon as possible. It is also recommended for Windows and macOS users to update to this version, as it contains additional fixes related to properties sanitization. There are no known workarounds for this vulnerability. ## CNA-Record (Kanon, cvelistV5) - CNA: **GitHub_M** - State: PUBLISHED - Stand: 2024-08-02 02:27:53 - CNA-CVSS: **9.7** (`CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`) ## CISA-Anreicherung (vulnrichment/ADP) - CISA-SSVC (Coordinator, v2.0.3): - Exploitation: **none** - Automatable: **no** - Technical Impact: **total** ## CVSS-Vektor ``` CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Netzwerk | bad | | AC Komplexität | Gering | bad | | PR Privilegien | Keine | bad | | UI Interaktion | Erforderlich | good | | S Scope | Verändert | bad | | C Vertraulichkeit | Hoch | bad | | I Integrität | Hoch | bad | | A Verfügbarkeit | Hoch | bad | ## Schwachstellen-Klasse - **CWE-150** — Improper Neutralization of Escape, Meta, or Control Sequences The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component. - **CWE-74** — Improper Neutralization of Special Elements in Output Used by a Downstream Component (Injection) The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. - **CWE-93** — Improper Neutralization of CRLF Sequences The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs. ## Angriffsmuster (CAPEC) - [CAPEC-41 — Using Meta-characters in E-mail Headers to Inject Malicious Payloads](https://capec.mitre.org/data/definitions/41.html) _(Severity: High)_ - [CAPEC-81 — Web Server Logs Tampering](https://capec.mitre.org/data/definitions/81.html) _(Severity: High)_ - [CAPEC-93 — Log Injection-Tampering-Forging](https://capec.mitre.org/data/definitions/93.html) _(Severity: High)_ - [CAPEC-134 — Email Injection](https://capec.mitre.org/data/definitions/134.html) _(Severity: Medium)_ ## Patch verfügbar (OSV) - 540d87637129bbdfb218167c005a766d7e9f308c (Commit) - 9932d4b289631d447f88ace09a2fabafe4cd5bd5 (Commit) ## Referenzen - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/sicherheitsluecken/cve-2024-32986/) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI WID (CSAF)_
