Fortinet has issued an advisory for a now-patched crucial safety flaw impacting Wi-fi LAN Supervisor (FortiWLM) that might result in disclosure of delicate info.
The vulnerability, tracked as CVE-2023-34990, carries a CVSS rating of 9.6 out of a most of 10.0.
“A relative path traversal [CWE-23] in FortiWLM could permit a distant unauthenticated attacker to learn delicate recordsdata,” the corporate stated in an alert launched Wednesday.
Nonetheless, in response to a description of the safety flaw within the NIST’s Nationwide Vulnerability Database (NVD), the trail traversal vulnerability may be exploited by an attacker to “execute unauthorized code or instructions through specifically crafted net requests.”
The flaw impacts the next variations of the product –
- FortiWLM variations 8.6.0 via 8.6.5 (Mounted in 8.6.6 or above)
- FortiWLM variations 8.5.0 via 8.5.4 (Mounted in 8.5.5 or above)
The corporate credited Horizon3.ai safety researcher Zach Hanley for locating and reporting the shortcoming. It is price mentioning right here that CVE-2023-34990 refers back to the “unauthenticated restricted file learn vulnerability” the cybersecurity firm revealed again in March as a part of a broader set of six flaws in FortiWLM.
“This vulnerability permits distant, unauthenticated attackers to entry and abuse builtin performance meant to learn particular log recordsdata on the system through a crafted request to the /ems/cgi-bin/ezrf_lighttpd.cgi endpoint,” Hanley stated on the time.
“This problem outcomes from the dearth of enter validation on request parameters permitting an attacker to traverse directories and skim any log file on the system.”
A profitable exploitation of CVE-2023-34990 may permit the risk actor to learn FortiWLM log recordsdata and pay money for the session ID of a consumer and login, thereby permitting them to use authenticated endpoints as nicely.
To make issues worse, the attackers may make the most of the truth that the online session IDs are static between consumer classes to hijack them and acquire administrative permissions to the equipment.
That is not all. An attacker may additionally mix CVE-2023-34990 with CVE-2023-48782 (CVSS rating: 8.8), an authenticated command injection flaw that has additionally been mounted in FortiWLM 8.6.6, to acquire distant code execution within the context of root.
Additionally patched by Fortinet is a high-severity working system command injection vulnerability in FortiManager that will permit an authenticated distant attacker to execute unauthorized code through FGFM-crafted requests.
The vulnerability (CVE-2024-48889, CVSS rating: 7.2) has been addressed within the under variations –
- FortiManager 7.6.0 (Mounted in 7.6.1 or above)
- FortiManager variations 7.4.0 via 7.4.4 (Mounted in 7.4.5 or above)
- FortiManager Cloud variations 7.4.1 via 7.4.4 (Mounted in 7.4.5 or above)
- FortiManager variations 7.2.3 via 7.2.7 (Mounted in 7.2.8 or above)
- FortiManager Cloud variations 7.2.1 via 7.2.7 (Mounted in 7.2.8 or above)
- FortiManager variations 7.0.5 via 7.0.12 (Mounted in 7.0.13 or above)
- FortiManager Cloud variations 7.0.1 via 7.0.12 (Mounted in 7.0.13 or above)
- FortiManager variations 6.4.10 via 6.4.14 (Mounted in 6.4.15 or above)
Fortinet additionally famous that quite a few older fashions, 1000E, 1000F, 2000E, 3000E, 3000F, 3000G, 3500E, 3500F, 3500G, 3700F, 3700G, and 3900E, are affected by CVE-2024-48889 supplied the “fmg-status” is enabled.
With Fortinet units turning into an assault magnet for risk actors, it is important that customers preserve their situations up-to-date to safeguard in opposition to potential threats.
