This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Authentication is required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 8.8. The following CVEs are assigned: CVE-2024-11949.
Microsoft today released updates to plug at least 70 security holes in Windows and Windows software, including one vulnerability that is already being exploited in active attacks.
The zero-day seeing exploitation involves CVE-2024-49138, a security weakness in the Windows Common Log File System (CLFS) driver — used by applications to write transaction logs — that could let an authenticated attacker gain “system” level privileges on a vulnerable Windows device.
The security firm Rapid7 notes there have been a series of zero-day elevation of privilege flaws in CLFS over the past few years.
“Ransomware authors who have abused previous CLFS vulnerabilities will be only too pleased to get their hands on a fresh one,” wrote Adam Barnett, lead software engineer at Rapid7. “Expect more CLFS zero-day vulnerabilities to emerge in the future, at least until Microsoft performs a full replacement of the aging CLFS codebase instead of offering spot fixes for specific flaws.”
Elevation of privilege vulnerabilities accounted for 29% of the 1,009 security bugs Microsoft has patched so far in 2024, according to a year-end tally by Tenable; nearly 40 percent of those bugs were weaknesses that could let attackers run malicious code on the vulnerable device.
Rob Reeves, principal security engineer at Immersive Labs, called special attention to CVE-2024-49112, a remote code execution flaw in the Lightweight Directory Access Protocol (LDAP) service on every version of Windows since Windows 7. CVE-2024-49112 has been assigned a CVSS (badness) score of 9.8 out of 10.
“LDAP is most commonly seen on servers that are Domain Controllers inside a Windows network and LDAP must be exposed to other servers and clients within an enterprise environment for the domain to function,” Reeves said. “Microsoft hasn’t released specific information about the vulnerability at present, but has indicated that the attack complexity is low and authentication is not required.”
Tyler Reguly at the security firm Fortra had a slightly different 2024 patch tally for Microsoft, at 1,088 vulnerabilities, which he said was surprisingly similar to the 1,063 vulnerabilities resolved in 2023 and the 1,119 vulnerabilities resolved in 2022.
“If nothing else, we can say that Microsoft is consistent,” Reguly said. “While it would be nice to see the number of vulnerabilities each year decreasing, at least consistency lets us know what to expect.”
If you’re a Windows end user and your system is not set up to automatically install updates, please take a minute this week to run Windows Update, preferably after backing up your system and/or important data.
System admins should keep an eye on AskWoody.com, which usually has the details if any of the Patch Tuesday fixes are causing problems. In the meantime, if you run into any problems applying this month’s fixes, please drop a note about in the comments below.
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Avraham Shalev and Nagaraju N Kodalapura discovered that some Intel(R)
Xeon(R) processors did not properly restrict access to the memory
controller when using Intel(R) SGX. This may allow a local privileged
attacker to further escalate their privileges. (CVE-2024-21820,
CVE-2024-23918)
It was discovered that some 4th and 5th Generation Intel(R) Xeon(R)
Processors did not properly implement finite state machines (FSMs) in
hardware logic. THis may allow a local privileged attacker to cause a
denial of service (system crash). (CVE-2024-21853)
It was discovered that some Intel(R) Processors did not properly restrict
access to the Running Average Power Limit (RAPL) interface. This may allow
a local privileged attacker to obtain sensitive information.
(CVE-2024-23984)
It was discovered that some Intel(R) Processors did not properly implement
finite state machines (FSMs) in hardware logic. This may allow a local
privileged attacker to cause a denial of service (system crash).
(CVE-2024-24968)
Multiple security vulnerabilities were discovered in python-aiohttp,
a HTTP client/server for asyncio, which could result in denial of
service, directory traversal, CRLF injection or request smuggling.
