CVE-2024-20506 (GCVE-0-2024-20506)

Vulnerability from cvelistv5 – Published: 2024-09-04 21:28 – Updated: 2025-11-03 21:52

Title

ClamAV Privilege Handling Escalation Vulnerability

Summary

A vulnerability in the ClamD service module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and 0.103.11 and all prior versions could allow an authenticated, local attacker to corrupt critical system files. The vulnerability is due to allowing the ClamD process to write to its log file while privileged without checking if the logfile has been replaced with a symbolic link. An attacker could exploit this vulnerability if they replace the ClamD log file with a symlink to a critical system file and then find a way to restart the ClamD process. An exploit could allow the attacker to corrupt a critical system file by appending ClamD log messages after restart.

Una vulnerabilidad podr\u00eda permitir que el atacante corrompa un archivo cr\u00edtico del sistema a\u00f1adiendo mensajes de registro de ClamD despu\u00e9s del reinicio.\"}],\"affected\":[{\"source\":\"psirt@cisco.com\",\"affectedData\":[{\"vendor\":\"Cisco\",\"product\":\"ClamAV\",\"defaultStatus\":\"unknown\",\"versions\":[{\"version\":\"1.4.0\",\"status\":\"affected\"},{\"version\":\"1.3.2\",\"status\":\"affected\"},{\"version\":\"1.0.6\",\"status\":\"affected\"},{\"version\":\"1.0.5\",\"status\":\"affected\"},{\"version\":\"1.0.4\",\"status\":\"affected\"},{\"version\":\"1.0.3\",\"status\":\"affected\"},{\"version\":\"1.0.2\",\"status\":\"affected\"},{\"version\":\"1.0.1\",\"status\":\"affected\"},{\"version\":\"1.0.0\",\"status\":\"affected\"},{\"version\":\"1.2.x\",\"status\":\"affected\"},{\"version\":\"0.105.x\",\"status\":\"affected\"},{\"version\":\"0.104.x\",\"status\":\"affected\"},{\"version\":\"0.103.11\",\"status\":\"affected\"},{\"version\":\"0.103.10\",\"status\":\"affected\"},{\"version\":\"0.103.9\",\"status\":\"affected\"},{\"version\":\"0.103.8\",\"status\":\"affected\"},{\"version\":\"0.103.7\",\"status\":\"affected\"},{\"version\":\"0.103.6\",\"status\":\"affected\"},{\"version\":\"0.103.5\",\"status\":\"affected\"},{\"version\":\"0.103.4\",\"status\":\"affected\"},{\"version\":\"0.103.3\",\"status\":\"affected\"},{\"version\":\"0.103.2\",\"status\":\"affected\"},{\"version\":\"0.103.1\",\"status\":\"affected\"},{\"version\":\"0.103.0\",\"status\":\"affected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"psirt@cisco.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H\",\"baseScore\":6.1,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":4.2},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H\",\"baseScore\":6.1,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":4.2}],\"ssvcV203\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"ssvcData\":{\"timestamp\":\"2024-09-05T13:34:43.487532Z\",\"id\":\"CVE-2024-20506\",\"options\":[{\"exploitation\":\"none\"},{\"automatable\":\"no\"},{\"technicalImpact\":\"partial\"}],\"role\":\"CISA Coordinator\",\"version\":\"2.0.3\"}}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-754\"}]},{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-754\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"0.103.12\",\"matchCriteriaId\":\"C21D8C4B-CEBE-422C-A103-B516EBCC34B6\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"0.104.0\",\"versionEndExcluding\":\"1.0.7\",\"matchCriteriaId\":\"8D3AF611-42CD-4EC8-9A2A-89AEC62A3D6E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"1.2.0\",\"versionEndExcluding\":\"1.3.2\",\"matchCriteriaId\":\"DD0EA13B-FFC9-4385-8691-38A90DCE774F\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:clamav:clamav:1.4.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"9D7F43F7-EF41-4CB7-A013-6A8F274F973D\"}]}]}],\"references\":[{\"url\":\"https://blog.clamav.net/2024/09/clamav-141-132-107-and-010312-security.html\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Release Notes\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2024/12/msg00004.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}",

GHSA-H5FR-Q576-Q7RV

Vulnerability from github – Published: 2024-09-05 00:31 – Updated: 2025-11-04 00:31

Details

The vulnerability is due to allowing the ClamD process to write to its log file while privileged without checking if the logfile has been replaced with a symbolic link. An attacker could exploit this vulnerability if they replace the ClamD log file with a symlink to a critical system file and then find a way to restart the ClamD process. An exploit could allow the attacker to corrupt a critical system file by appending ClamD log messages after restart.

Severity

6.1 (Medium)
