June 22, 2022Ravie Lakshmanan
QNAP, Taiwanese maker of network-attached storage (NAS) devices, on Wednesday said it's in the process of fixing a critical three-year-old PHP vulnerability that could be abused to achieve remote code execution. "A vulnerability has been reported to affect PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24, and 7.3.x below 7.3.11 with improper nginx config," the hardware vendor  said  in an advisory. "If exploited, the vulnerability allows attackers to gain remote code execution." The vulnerability, tracked as  CVE-2019-11043 , is rated 9.8 out of 10 for severity on the CVSS vulnerability scoring system. That said, it's required that Nginx and php-fpm are running in appliances using the following QNAP operating system versions - QTS 5.0.x and later QTS 4.5.x and later QuTS hero h5.0.x and later QuTS hero h4.5.x and later QuTScloud c5.0.x and later "As QTS, QuTS hero or QuTScloud does not have nginx installed by default, QNAP NAS are not aff

May 06, 2022Ravie Lakshmanan
QNAP, Taiwanese maker of network-attached storage (NAS) devices, on Friday released security updates to patch nine security weaknesses, including a critical issue that could be exploited to take over an affected system. "A vulnerability has been reported to affect QNAP VS Series NVR running QVR," QNAP  said  in an advisory. "If exploited, this vulnerability allows remote attackers to run arbitrary commands." Tracked as  CVE-2022-27588  (CVSS score: 9.8), the vulnerability has been addressed in QVR 5.1.6 build 20220401 and later. Credited with reporting the flaw is the Japan Computer Emergency Response Team Coordination Center (JPCERT/CC). Aside from the critical shortcoming, QNAP has also resolved three high-severity and five medium-severity bugs in its software - CVE-2021-38693  (CVSS score: 5.3) - A  path traversal vulnerability  in thttpd affecting QNAP devices running QTS, QuTS hero, QuTScloud, and QVR Pro Appliance, leading to information disclosure C

QNAP Advises to Mitigate Remote Hacking Flaws Until Patches are Available
April 27, 2022Ravie Lakshmanan
Network-attached storage (NAS) appliance maker QNAP on Wednesday  said  it's working on updating its QTS and QuTS operating systems after Netatalk last month released patches to contain seven security flaws in its software. Netatalk  is an open-source implementation of the Apple Filing Protocol ( AFP ), allowing Unix-like operating systems to serve as file servers for Apple macOS computers. On March 22, 2022, its maintainers released  version 3.1.13  of the software to resolve major security issues — CVE-2021-31439 ,  CVE-2022-23121 ,  CVE-2022-23122 ,  CVE-2022-23123 ,  CVE-2022-23124 ,  CVE-2022-23125 , and  CVE-2022-0194  — that could be exploited to achieve arbitrary code execution. "This vulnerability [CVE-2022-23121] can be exploited remotely and does not need authentication," NCC Group researchers  noted  last month. "It allows an attacker to get remote code execution as the 'nobody' user on the NAS. This user can access private shares that would

QNAP Advises Users to Update NAS Firmware to Patch Apache HTTP Vulnerabilities
April 22, 2022Ravie Lakshmanan
Network-attached storage (NAS) appliance maker QNAP on Thursday said it's investigating its lineup for potential impact arising from two security vulnerabilities that were addressed in the Apache HTTP server last month. The critical flaws, tracked as  CVE-2022-22721 and CVE-2022-23943 , are rated 9.8 for severity on the CVSS scoring system and impact Apache HTTP Server versions 2.4.52 and earlier - CVE-2022-22721  - Possible buffer overflow with very large or unlimited LimitXMLRequestBody CVE-2022-23943  - Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server Both the vulnerabilities, alongside CVE-2022-22719 and CVE-2022-22720, were remediated by the project maintainers as part of  version 2.4.53 , which was shipped on March 14, 2022. "While CVE-2022-22719 and CVE-2022-22720 do not affect QNAP products, CVE-2022-22721 affects 32-bit QNAP NAS models, and CVE-2022-23943 affects users who have enabled mod_sed in Apache HTTP Server on their QNAP device,"

QNAP Warns of OpenSSL Infinite Loop Vulnerability Affecting NAS Devices

QNAP Warns of OpenSSL Infinite Loop Vulnerability Affecting NAS Devices
March 30, 2022Ravie Lakshmanan
Taiwanese company QNAP this week revealed that a selected number of its network-attached storage (NAS) appliances are affected by a recently-disclosed bug in the open-source OpenSSL cryptographic library. "An infinite loop vulnerability in OpenSSL has been reported to affect certain QNAP NAS," the company  said  in an advisory published on March 29, 2022. "If exploited, the vulnerability allows attackers to conduct denial-of-service attacks." Tracked as  CVE-2022-0778  (CVSS score: 7.5), the issue relates to a bug that arises when parsing security certificates to trigger a denial-of-service condition and remotely crash unpatched devices. QNAP, which is currently investigating its line-up, said it affects the following operating system versions – QTS 5.0.x and later QTS 4.5.4 and later QTS 4.3.6 and later QTS 4.3.4 and later QTS 4.3.3 and later QTS 4.2.6 and later QuTS hero h5.0.x and later QuTS hero h4.5.4 and later, and QuTScloud c5.0.x To date, t

'Dirty Pipe' Linux Flaw Affects a Wide Range of QNAP NAS Devices

'Dirty Pipe' Linux Flaw Affects a Wide Range of QNAP NAS Devices
March 14, 2022Ravie Lakshmanan
Network-attached storage (NAS) appliance maker QNAP on Monday warned of a recently disclosed Linux vulnerability affecting its devices that could be abused to elevate privileges and gain control of affected systems. "A local privilege escalation vulnerability, also known as 'Dirty Pipe,' has been reported to affect the Linux kernel on QNAP NAS running QTS 5.0.x and QuTS hero h5.0.x," the company  said . "If exploited, this vulnerability allows an unprivileged user to gain administrator privileges and inject malicious code." The Taiwanese firm said it's continuing to thoroughly  investigate its product line  for the vulnerability and that QNAP NAS devices running QTS versions 4.x are immune to the Dirty Pipe flaw. Tracked as  CVE-2022-0847  (CVSS score: 7.8), the shortcoming resides in the Linux kernel that could permit an attacker to overwrite arbitrary data into any read-only files and allow for a complete takeover of vulnerable machines. "A

QNAP Warns of DeadBolt Ransomware Targeting Internet-Facing NAS Devices

QNAP Warns of DeadBolt Ransomware Targeting Internet-Facing NAS Devices
January 27, 2022Ravie Lakshmanan
Taiwanese company QNAP has warned customers to secure network-attached storage (NAS) appliances and routers against a new ransomware variant called DeadBolt . "DeadBolt has been widely targeting all NAS exposed to the Internet without any protection and encrypting users' data for Bitcoin ransom," the company  said . "QNAP urges all QNAP NAS users to […] immediately update QTS to the latest available version." A query on IoT search engine Censys shows that at least 3,687 devices have been encrypted by the DeadBolt ransomware so far, with most NAS devices located in the U.S., Taiwan, France, Italy, the U.K., Hong Kong, Germany, the Netherlands, Poland, and South Korea. In addition, QNAP is also urging users to check if their NAS devices are public-facing, and if so, take steps to turn off the port forwarding function of the router and disable the Universal Plug and Play ( UPnP ) function of the QNAP NAS. The advisory comes as  Bleeping Computer  revealed t
