Public Vulnerabilities & CVEs found by YLabs. All releases are governed by our Vulnerability Disclosure Policy.

A cross-site scripting (XSS) vulnerability in the check_login function of S.I.R.I. s.r.l WI400 between v.8 and v.11 included allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the “f” parameter.

Severity: Medium

OverIT projects based on the same Geocall-Framework at level v. < 8, an authenticated user who has the “Test Trasformazione xsl” functionality enabled can exploit an XSLT Injection vulnerability in order to achieve remote code execution (RCE). The vulnerability is triggered by sending a specific XSL tag inside the XML field.

Severity: Low

OverIT projects based on the same Geocall-Framework at level v. < 8, an authenticated user who has the “Test Trasformazione xsl” functionality enabled can exploit an XXE vulnerability to read arbitrary files from the filesystem. The vulnerability is triggered by sending a specific XSL tag inside the XML field.

Severity: High


Wowza Streaming Engine v.<= 4.8.16+1 (build 20211129092949) is vulnerable to the Log4j JNDI injection, affecting the 'j_username' username field, in the login page as well as other HTTP headers. Attackers exploiting this issue will be able to achieve remote code execution (RCE) in the context of the NT AUTHORITY\SYSTEM Windows user managing the service.
All vendors affected by the Log4j vulnerability must use the CVE-2021-44228 when referring to this vulnerability in their own products.
At present, MITRE does not offer an option for a vendor to associate its own unique CVE ID with this same underlying vulnerability.

Severity: Medium

Clementine Music Player v. <= 1.3.1, in libgstreamer-1.0-0.dll (F1CC318CA54B8BC35179A48DAEBB94DF741D9E3B) module, is affected by a Read Access Violation on Block Data Move (potential Stack Overflow), affecting the MP3 file parsing functionality at memcpy+0x265.

The vulnerability is triggered when the user opens a crafted MP3 file or loads a remote stream URL that is mishandled by Clementine.
Attackers could exploit this issue to cause a crash (DoS) of the clementine.exe process or achieve arbitrary code execution in the context of the current logged-in Windows user.

Severity: High

Crucial by Micron Technology, Inc Ballistix MOD Utility v.<= 2.0.2.5 is vulnerable to multiple Privilege Escalation (LPE/EoP) vulnerabilities in the MODAPI.sys driver component.

All the vulnerabilities are triggered by sending specific IOCTL requests and will allow to:

  • Directly interact with physical memory via the MmMapIoSpace function call, mapping physical memory into a virtual address user-space.
  • Read/write Model-Specific Registers (MSRs) via the __readmsr/__writemsr functions calls.
  • Read/write 1/2/4 bytes to or from an IO port.

Attackers could exploit these issues to achieve local privilege escalation from low-privileged users to NT AUTHORITY\SYSTEM.

Severity: High

NVIDIA GeForce Experience v.<= 3.21 is affected by an Arbitrary File Write vulnerability in GameStream plugins where log files are created using NT/System level permissions, which lead to Elevation of Privileges (EoP) to Code Execution.

Severity: High

FastStone Image Viewer v.<= 7.5 is affected by a user mode Write Access Violation at 0x00402d7d, triggered when a user opens or views a malformed CUR file that is mishandled by FSViewer.exe. Attackers could exploit this issue for a Denial of Service (DoS) or possibly to achieve code execution.

Severity: High

FastStone Image Viewer v.<= 7.5 is affected by a Stack-based Buffer Overflow at 0x005BDF49, affecting the CUR file parsing functionality ('BitCount' file format field), that will end up corrupting the Structure Exception Handler (SEH). Attackers could exploit this issue to achieve code execution when a user opens or views a malformed/specially crafted CUR file.
