A path traversal vulnerability in the Python setuptools library allows attackers with limited system access to write files outside the intended temporary directory by manipulating package download URLs. This flaw bypasses basic filename sanitization and can lead to unauthorized overwrites of important system files, creating opportunities for further compromise. While it doesn't expose data or require user interaction, it poses a high integrity risk and is especially concerning in environments that rely on automated package handling or internal tooling built on setuptools.

Threats
Impact
Moderate
A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected.

Exploit Status
CISA: https://www.cisa.gov/known-exploited-vulnerabilities-catalog
Impact
Important
The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.

Full admin rights aren\u0027t needed but a user with no access at all will be unable to exploit this vulnerability.\n* The vulnerability impacts the integrity of the system within the same security boundary\u2014it does not enable access or compromise across trust boundaries (e.g., from one container to another or from user space to kernel).\n* Successful exploitation only allows the attacker to \"create\" new files. The vulnerability does not provide access to existing files and by an extension to any confidential information. \n* Arbitrary file writes can overwrite critical config files, executables, or scripts. This can lead to persistent code execution, system misconfiguration, or unauthorized behavior, especially in automated environments. While overwriting critical files could theoretically lead to service disruption, the vulnerability in isolation does not inherently cause denial of service.

When sg_inq --export processes SCSI device identification data from VPD page 0x83, the SCSI name string designator (type 8) and the ATA vendor-ID subfield are printed without sanitizing embedded control characters. A crafted SCSI/USB device can embed a newline in this field, splitting sg_inq\u0027s udev KEY=VALUE output into two lines and injecting an arbitrary udev property, including REMOVE_CMD. On systems whose default udev rules invoke sg_inq --export for SCSI device identification and act on REMOVE_CMD when a device is removed, this allows a local attacker with physical access to a USB/SCSI port to achieve arbitrary command execution as root simply by disconnecting the crafted device.\n\nExploitation requires physical access to attach the malicious device, consistent with Red Hat\u0027s Physical (AV:P) attack vector scoring. The upstream fix (udev-conforming character escaping for this field) has not yet been included in any tagged sg3_utils release; all Red Hat-shipped versions of sg3_utils in the 1.34-1.48 range are affected.",

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
